XREF Keeps Moving

Opening a file with an Xref, or Xrefs, after saving may appear to be moving/relocating on their own. Explore INSBASE and UCS commands as the most often fix that works:

Both the value of INSBASE variable and the current UCS need to be consistent in both the source and target file(s). The easiest way to keep all of this straight is to set UCS command settings to World and INSBASE variable setting to 0,0,0.
Use 0,0,0 as the insertion point when you INSERT the Xref. The same if you are creating an external block with WBLOCK command. ◦

XREF Keeps Moving

Dialog Window or Command Pop-up missing

You start a command like OPEN or SAVEAS, and instead of a pop-up to select file location and name, you get prompted at the command line to manually enter the information.

FILEDIA variable is turned off: at the command line, type it and when ask, type 1 (one) to turn it on. This variable is designed to suppress display of file navigation dialog boxes if set to 0 (zero).

It affects many other commands, including BMPOUT, CUILOAD, CUIUNLOAD, IMPORT, JPGOUT, NEW, OPEN, PNGOUT, PUBLISH, RECOVER, RECOVERALL, SAVEAS, SCRIPT, TIFOUT, VSLIDE, WBLOCK and XREF among others.

A similar variable, CMDDIA, used to affect more commands in older LT versions, but in many of the latest versions only affect QLEADER;s in-place text editor. ◦

Dialog Window or Command Pop-up missing

Dialog Window or Command Pop-up gone

You start the command (OPEN, LAYER, BHATCH etc.) and nothing happens: LT acts like the command is running, but you have nothing on screen. You are able to cancel the command.

Your pop-up may be off screen: start themmand, on the keyboard use the combination of ALT+SpaceBar+M then use the arrow keys on your keyboard to nudge it back to view (this is a Windows feaure, you can use it to recover any lost pop-up in LT or other programs).
You can also change the resolution of your monitor to lower settings, the layer manager will show, move it to be centered, then change resolution back. ◦

Two commands to Explode Entities

EXPLODE command allows you to convert complex objects to their constituent components. Explode Mtext to get Text. Explode Plines, Mlines, Hatches, Dimensions and Leaders into Lines, Arcs, Text, etc. Explode Blocks to their component parts.
Exploding a Block sometimes gives us undesirable results. Often a Block is created from entities on Layer 0, so that it can be inserted on any Layer and thus inherit the properties of the insertion Layer. When exploding a Block of this type, all the components revert back to Layer 0.
XPLODE command (notice the missing E) works similarly to EXPLODE except it gives you the opportunity to override component entity properties. You can control the target Layer, Line type, Line weight, and Color, or Inherit all properties from the Block insertion.
You can also control what you explode individually, or globally (covers all entities being exploded).

Explore both in HELP in LT for usage instructions. ◦

Import Spreadsheets and Export Tables from LT

To import a spreadsheet (MSExcel used here for an example) into AutoCAD LT:

1. Open the MSExcel file.
2. Highlight the desired cells you want to import into LT.
3. Choose Edit-->Copy from the pull down menu (copy selected cells to clipboard)
4. Minimize MSExcel, do not close the program or you will lose the selected cells copied to the clipboard.
5. Open LT and a new or current drawing.
6. Choose Edit > Paste Special from the pull down menu.
7. In the Paste Special dialogue box, choose "AutoCAD LT Entities".
8. Choose an insertion point for the table. Remeber that the table size, text height ..etc, is based on the current Table Style.

To export from AutoCAD LT to a spreadsheet program (MSExcel used here for an example):

1. Open LT and a drawing containing a completed table.
2. Select the table and right-click.
3. In the right-click menu choose the Export option.
4. Save the table in a folder. Notice that the table is saved as a .CSV file (Comma Delimited).
5. In MSExcel, go to File-->Open in the pull down menu.
6. In the Open dialogue box, change the "Files of Type" option at the bottom to "All Files".
7. Navigate to the folder containing the .CSV file and select the file to open.

File Name missing at PDF prompt

Plotting to PDF using any free or purchased (or built in driver in LT2007 and higher), or any other 3rd party driver to create a file is a convenience until the file name prompt stops echoing the DWG file name and presents the user with an empty box to fill.

FULLPLOTPATH is a variable added in 2006 to help overcome AutoCAD/LT's ability to overwhelm drivers that can't handle receiving the full path of the file in the plot. SImply type it at the command line in LT, and when prompted set it to 0 (zero). Your PDF driver should start placing your DWG file name in the box when prompting you for the PDF file's name.

And your troublesome Plotter or Printer driver may start behaving as well if you've had issues with them and LT. ◦

Fail to Create CommCntrClientSink object!

Starting LT presents this error message: you can click OK and get into LT but find thatProperties and other features do not function. The cause is usually after the use of a Windows Registry Cleaner that many websites tout as necessary.

In most circumstances, using that Registry Cleaner's Undo or Restore feature fixes the problem, most quality products also include an exclusion option where you can add AutoCAD/LT to the list of programs not to touch.

If you use a freebie or a bargain cleaner, they don't restore or recover well. A repair reinstall of LT fixes the problem as noted HERE.
If not, you need to go a step further and completely uninstall all Autodesk products on your system as discussed HERE, then reinstalling them after a Windows restart.
Click on this for a GOOGLE search on the topic and other solutions posted.

Don't forget to backup all your LT customizations first, often, and regularly. ◦

Recovering Backup files

LT offers several backup files for you to recover from should your DWG file become corrupt. Below is the list of these files and how you can use them to help:

• BAK files are backup files created on manual Saves, they reside in the same folder as your DWG file and all you have to do to recover one is to rename the file extension (if you have that feature turned on in Windows Explorer) from BAK to DWG.
  Of course, you need to turn on BAK file creation first to get them: See screenshot below in OPTIONS command. Some I.T. personnel may not realize how important these files are so you need to push to have them if necessary for instant recovery as opposed to I.T.'s day-old recovery.



• SV$ files are automatic timed backups of drawings created by turning on AUTOSAVE in LT. This should never be considered a replacement for a manual save, this feature exists solely as a backup to the above in case of an LT or system crash only: this autosave file is always deleted on successful AutoCAD/LT exit. These files are stored in the temp files folder under
  You need to turn on the Autosave feature first to get them: See screenshot below in OPTIONS command. Rename the file extension (if you have that feature turned on in Windows Explorer) from SV$ to DWG.



• AC$ files are temporary AutoCAD working files for various functions (undo, hidden lines...), ac$ files do not contain drawing data, you can't use them for anything or recover any data from them for your use.

Recovering Backup files

Design Center's other features

In addition to the Search features discussed earlier HERE, LT's Design Center Floating or docked Palette (ADCENTER command or CTRL+2) can do much more:

• You can import content from another DWG file into your current one, such as Linetypes, Layers, Text Styles, Dim Styles, Table Styles, Blocks, Xrefs and Layouts.
• Using the Open Drawings tab, you can access the above content from ALL the current files you have open at the time, so you don't have to go browsing for the files first. You can also use the History tab the same way, except to access files you recently opened in LT.
• You can use ADCNAVIGATE command to go directly to a folder before you open ADCENTER: great customizing tip if you have many folders that you access regularly for content.
• You can drag and drop a DWG file into your current file to INSERT it as a block. If you drag that DWG file with the mouse's right-key, you get the option to start the full INSERT command pop-up, or attach that file as an XREF.
• You can set a folder to be the default go-to folder everytime you start Design Center: in the Folders tab, navigate to that folder, then right-click and select Set As Home.
• You can create a ToolPalette of all the dwg files from ADCENTER without doing it manually yourself: in the Folders tab, navigate to that folder, then right-click and select Create Toolpalette Of Blocks.
• You can drag and drop single Hatch Patterns from .pat files into your file, without using BHATCH command or placing them in any search path.

Right-click button settings

Many 'old-school' AutoCAD users do one thing the first time they start a new AutoCAD version: kill right-clicking feature for the 'faster' option of having it set to simply function from the keyboard. You will miss half the features of LT by doing this unfortunately, and your imagined speed gain is lost.

LT2004 and higher offer a compromise that is more productive than either option alone: A new time sensitive right-click. When this ability is turned on, a quick click of the right mouse button is the same as pressing on the keyboard. Holding down the right mouse button longer than the specified time yields a context sensitive menu (when appropriate).

To set, start OPTIONS command, choose the User Preferences tab, turn on Shortcut Menus in Drawing Area selection, choose the Right-click Customization button: turn on Time Sensitive Right Click.
Change the time interval as needed until you find the setting most comfortable with your hand and mouse.

Right-click button settings

Text plots in outline only

This is a limitation of using Windows TrueType Fonts (TTF), not found in AutoCAD's SHX fonts (those stick-like hideous fonts we all love). The fix can be one or many of the following:

• Set the FILL command to on.
• Set the FILLMODE system variable to 1.
• Set the TEXTFILL system variable to 1.
• In the Plot dialog box, clear Hide Objects. If you need this setting for the rest of your drawing, you will need to change to SHX fonts in your text styles.
• Turn off the Hideplot property of the viewport. If you need this setting to achieve a desired plot ability, you will need to either change to SHX fonts in your text style or place the text in Paperspace out of the viewport.
• Turn off Shadeplot > Hidden Property of Viewport in LT2004, LT2005, and LT2006.

No Linetypes in Layouts

LTSCALE is set and the linetypes in Modelspace appear as set: clicking over to Paperspace (Layout) shows no linetypes in the viewport. REGEN command does not solve the problem.

The user must change the setting for the layout variable PSLTCALE (or better yet, copy a preset Layout from a template that is set correctly instead of randomly starting a layout from scratch). PSLTSCALE controls linetype scaling of objects displayed in paperspace viewports.

The variable has two setting options:

0 (or off) Linetype dash lengths are based on the viewport scale, they are NOT the same spacing.

1 (or on) If TILEMODE is set to 0, dash lengths are based on paper space drawing units, even for objects in model space. For any linetype, the dash lengths of a line in a viewport are the same as the dash lengths of a line in paper space.

The Global Scale Factor value controls the LTSCALE system variable, which changes the linetype scale globally for both new and existing objects.
The Current Object Scale value controls the CELTSCALE system variable, which sets the linetype scale for new objects. The CELTSCALE value is multiplied by the LTSCALE value to get the displayed linetype scale. You can easily change linetype scales in your drawing either individually or globally. ◦

No Linetypes in Layouts

Entering Surveyor Bearing and Distance

Set the appropriate units in the UNITS command: Angular units to Surveyor, choose the direction button, set Angle Direction to East, Rotation to counter clockwise. Start LINE or PLINE command and enter the points needed as relative polar coordinates.
For example:

Command: LINE
Start Point: Select a start point
Next Point: @ 123.45 < N 45 D 10' 15" E
Next Point: @ 678.90 < S 25 D 20' 25" W

NOTE: no spaces needed between point entry text, shown here just for clarity.

Syntax description: @ sign is for relative to the start or last point. Next comes the Distance. Last is the Bearing. Its enclosed in the quadrant NE, NW, SE, SW. Letter D is to indicate the degrees. ◦

Just type it at the command line

Many tips offered in this blog list the command or variable by name, not by menu location or toolbar button, and this confuses some readers that are more confortable hunting down such locations for convenience sake and ease of use.

Not all commands or variables exist in LT as a menu pick or a toolbar button, so feel free to just TYPE the command at the command prompt in LT (if you turned it off or hid it, reposition it and turn it back on): without the command line available you are also missing out on many prompts and additional feedback LT is providing you. ◦

Turn on the MAX in LT

A Layout with many viewports only displays some, or worse, only one viewport content at a time, but clicking inside of of the others activates it but turns on a previously displayed one.
Explore MAXACTVP variable in HELP, it controls how many active viewports you can see at anyone time. Limit is 64 though.

You need to create a large ARRAY and notice that LT hits a limits and stops. You can change this limit by setting the MaxArray system registry variable using SETENV and entering a number between 100 and 10000000. MaxArray must be entered with the capitalization shown.

You create, or try to, a very dense hatch pattern and LT objects that the hatch is too small or the dash length is too short: first make sure that SOLID hatch is not what you really need. If that's not the case, the hatch object limit is set by the MaxHatch environment setting: change this limit by setting the MaxHatch system registry variable using SETENV and entering a number between 100 and 10000000. MaxHatch must be entered with the capitalization shown.

LAYER command is not sorting all your file's layers or blocks alphabetically or any other order you select: explore MAXSORT variable in HELP in LT, inclrease the number displayed until the sorting problem is resolved. ◦

GEDIT or GEDIT 3 Error messages

LT2002 could just not get rid of this problem once it showed up, and Autodesk never provided a permanent fix: some users had some luck turning off video card hardware acceleration but most of us never really found a fix. It was often, but not exclusively triggered by a Pan or Zoom function.

LT2004 required the Service Patch to be installed to remove the symptom/cause noted above. If you have done this or are using a version of LT higher than 2004 and you still get this problem, so far it's been solely attributed to a conflict on your PC with another software package, and often requires that software package to be removed or updated.

JPG, PNG, BMP, TIFF and more from LT

Similar to the EPS file creation tip below, LT has the ability to create many popular Raster File formats as well. These allow you to generate graphic content for other apps like MSWord or MSPowerpoint from your AutoCAD files.

To use this ability, you first need to set up a Raster File plotter, then PLOT to that format. Setup is as follows:

1. Choose File > Plotter Manager.
2. Choose 'Add-A-Plotter Wizard'.
3. Choose Next, then Next again (accepting My Computer).
4. Under Manufacturers, choose 'Raster File Formats'.
5. Under Models, choose the raster file format you need.
6. Choose Next until the Finish button becomes available. Note that some additional options exist to set if you so desire, including the ability to control the raster file background color.

Now start PLOT command, select the plotter you just create, and use any or all of PLOT command's options and features to create your custom raster file.

Simple and quick entities Alignment

To align several drawing entities quickly (blocks or text, e.g. left-align texts to a border) just select all text objects to be aligned (justified), open the PROPERTIES palette and set a new common X-coordinate (Geometry: X-position) or Y-coordinate (Geometry: Y-position).

You can use the PROPERTIES palette to adjust text justification before changing its alignment. ◦

WBLOCK command hidden feature

WBLOCK command is a create tool for creating a new file from content in your current open drawing. Simply select the entity or entities, give the selection a new name, and a new file with that name is created at a location of your choice on your PC or network.
The command line version, -WLBOCK (note the dash), has some interesting additional abilities:

1. Entering the name of an existing block writes that block to an external file. Note that this function is not available with an external reference (xref) or one of its dependent blocks.
2. Entering an equal sign (=) specifies that the existing block and the output file have the same name. Note that if no block of that name exists in your open drawing file, the prompt is displayed again and you must select another block name.
3. Entering an asterisk (*) writes the entire drawing to the new output file, except for unreferenced symbols. Model space objects are written to model space, and paper space objects are written to paper space. A great way to creat a new file but still maintain existing layouts.

Note: After the file is created, the selected objects are deleted from the drawing. You can use OOPS to restore the objects.

To temporarily override the locked status, hold the Ctrl key while moving the toolbar or window. The lock status is also controlled by the LOCKUI system variable, with the following options:

0 Toolbars and windows not locked
1 Docked toolbars locked
2 Docked or anchored windows locked
4 Floating toolbars locked
8 Floating windows locked ◦

Redefine block entities to ByLayer

Many seasoned AutoCAD users prefer to create blocks on layer 0 (zero), and set the block entities to Bylayer so as to have maximum flexibility possible in block placement and Properties controls.

To repair such a setting in LT2008 or higher, redefine the block(s) with the SETBYLAYER command.
In older AutoCAD versions you can use the BEDIT or BLOCK commands to redefine the block(s), choice is limited by your LT version. ◦

MULTIPLE command's intersting ability

Have you ever needed a command to repeat, and repeat, and repeat, as you do something very repetitive over and over again? MULTIPLE command is what you need.

It has a very simple function: it repeats whatever command you type right after it. For example, you need to use MOVE or FILLET or CHAMFER commands etc. on many objects individually. At the command line, type MULTIPLE then the command you want to repeat, then use as normal. Every thime you finish the command, it restarts. To cancel, simply tap the ESC key on your keyboard.

To things to note about this command: it does not repeat any parameters within the command, it just repeast the command as if you just started it. It also does not work on commands that present you with a dialog box. ◦

Create an EPS file in LT

LT can create many types of file formats for use with other programs, much more than the very limited EXPORT command many casual users search for answers. These are provided in the form of plotter drivers that you create and use with PLOT command.
The following is a tip to creating EPS files for import into graphics programs like Adobe's Photoshop and Illustrator programs:

• At the command line, type PLOTTERMANAGER
• Double click on Add-A-Plotter Wizard
• Choose My Computer
• Select Manufacturers: Adobe
• Select Models: Postscript Level 1 Plus
• Check the option to Plot to File
• Name this new driver EPS

Now you can PLOT the drawing using this new EPS printer. Select the corresponding CTB or STB to control lineweight and linetype, and any other options in PLOT's window to get the exact output you need. ◦

Viewport Zooms after entering

If double-clicking inside a viewport causes the display inside to what is best described as Zoom>Extents, your file has a setting that needs to be changed inside each and every viewport in each and every layout in this one DWG file.

First, lock your viewport (a great habit on it's own), then double-click inside it. At the command line type UCSFOLLOW, and set it to 0 (zero). You may now safely unlock your viewport, if you must. Don't forget to repeat in every other viewport in this file.

Searching for LT content

LT provides a great tool for searching DWG files for content like BLOCKS, DIMSTYLES, DRAWINGS, HATCH PATTERNS, LAYERS, LAYOUTS, LINETYPES, TEXTSTYLES etc.

Start Design Center (ADCENTER command or CTRL+2), click on the Search button, and use the new pop-up to select what you are looking for plus other search parameters to find your content quickly.

ADCENTER command can also be used to identify where a drawing file is being Xrefed.

Recover Defective Drawing Files

Under some circumstances, it is possible that a drawing file becomes defective. This can result from hardware problems or transmission errors. If a drawing file is corrupt, you might be able to recover it.

• Repair a Damaged Drawing File
  If a drawing file is damaged, you can recover some or all of the data by using commands to find and correct errors. When an error occurs, diagnostic information is recorded in the aclt.err file, which you can use to report a problem.
  A drawing file is marked as damaged if corrupted data is detected, or if you request that the drawing be saved after a program failure. If the damage is minor, sometimes you can repair the drawing simply by opening it. Otherwise, you can use the following:
  RECOVER command. Performs an audit on, and attempts to open, any drawing file.
  RECOVERALL command (LT2008 and higher). Similar to recover, it additionally operates on all nested xrefs. The results are displayed in the Drawing Recovery Log window.
  AUDIT command. Finds and corrects errors in the currently open drawing file.
  
• Create and Restore Backup Files
  Backup files help ensure the safety of your drawing data. If a problem occurs, you can restore a drawing backup file. Computer hardware problems, power failures or surges, user mistakes, or software problems can cause errors in a drawing. By saving your work frequently, you can ensure a minimum of lost data if your system fails for any reason. If a problem occurs, you can restore a drawing backup file.
  In the Options dialog box, on the Open and Save tab, you can specify that backup files are created when you save drawings. If you do, each time you save a drawing, the previous version of your drawing is saved to a file with the same name and a .bak file extension. The backup file is located in the same folder as the drawing file.
  You can revert to your backup version by renaming the .bak file in Windows Explorer to a file with a .dwg extension. You may want to copy it to a different folder to avoid overwriting your original file.
  
• Recover from a System Failure
  A hardware problem, power failure, or software problem can cause this program to terminate unexpectedly. If this happens, you can restore the drawing files that were open. If the program fails, you can save your current work to a different file. This file uses the format, DrawingFileName_recover.dwg, where DrawingFileName is the file name of your current drawing.
  After a program or system failure, the Drawing Recovery Manager opens the next time you start AutoCAD LT. Drawing Recovery Manager displays a list of all drawing files (DWG and DWT) that were open.
  Note: Unsaved drawings that are open at the time of an unexpected failure are not tracked by the Drawing Recovery Manager. Be sure to save your work after you begin, and regularly thereafter.
  For each drawing, you can open and choose from the following files if they exist:
  DrawingFileName_recover.dwg
  DrawingFileName_a_b_nnnn.sv$
  DrawingFileName.dwg
  DrawingFileName.bak
  Note: The drawing, backup, and recover files are listed in the order of their time stamps—the time when they were last saved.
  Doubleclick a top-level drawing node listed under Backup Files to display up to four files as listed above. Right-click any node under Backup Files to display shortcut menu options.

Change the Default Drawing Folder

Each time you start AutoCAD/LT, the My Documents folder is the default path in each standard file selection dialog box. Alternatively, you can configure AutoCAD/LT to always default to a specified path by changing the default drawing folder using the REMEMBERFOLDERS system variable.
Restarting LT helps set it if it acts up after the change. ◦

TrustedDWG messages and concept

HELP in LT explains it as follows:

TrustedDWG™ Drawing Files
DWG, DWT, and DWS files that are created with Autodesk applications and RealDWG™-based applications are trusted by Autodesk. When you open a TrustedDWG file, the following icon displays in the application status bar or the drawing status bar.

If the DWGCHECK system variable is set to On (1), an alert box is displayed if:

• The drawing file format is AutoCAD Release 14 or later and
• The drawing file was not saved by an Autodesk application or RealDWG-based application.

LAYER tools built into LT

Starting with LT2007, almost all of the layer tools limited to Express Tools in full AutoCAD are now available as part of the core program. Below is an abbreviated list; unlike many free macros that LT users of earlier version used, these are not limited to current model or layout entities alone (they shoudl work on Xrefs and through layouts):

LAYCUR Changes the layer of selected objects to the current layer
LAYDEL Permanently deletes layer from drawing
LAYFRZ Freezes layers of selected objects
LAYISO Isolates layers of selected objects
LAYLCK Locks layer of selected object
LAYMCH Changes the layer of selected objects to the layer of a selected destination object
LAYMRG Merges two layers, and removes the first layer from the drawing
LAYOFF Turns of layers of selected objects
LAYON Turns on all layers in drawing
LAYTHW Thaws all layers
LAYTHW Thaws all layers in drawing
LAYULK Unlocks layers of selected object
LAYUNISO Turns on all layers that were turned off by the last LAYISO command.
LAYVPI Isolates an object's layer to the current viewport
LAYVPMODE Controls whether the layer utilities LAYISO, LAYFRZ and LAYOFF use VPFreeze or the standard layer Freeze or Off when used in a floating paper space viewport.
LAYWALK Dynamically displays objects on selected layers, more HERE
COPYTOLAYER to copy entities to another layer in your current file

If you are currently limited to older versions of LT, your choices are limited to macros available at many locations including our Add-Ons for your older versions and freely posted menu macro code at Autodesk's LT discussion area.

Problem opening a DWG file from Windows Explorer

AutoCAD/LT does not correctly open a DWG file from a Windows Explorer by double-clicking, but displays the message: "Windows cannot find '*.dwg'. Make sure you typed the name correctly, and then try again. To search for a file, click the Start button, and then click Search..." .
The problem seems to be the way AutoCAD/LT since version 2007 starts: instead of launching the program, file it goes through a 'launcher' instead.

There are several ways to fix this problem, two locations posted that seem to work for most users are at Autodesk's Discussion Area as well as HERE. ◦

Problem opening a DWG file from Windows Explorer

COPY command's Multiple preset

For several versions now, LT's COPY command has defaulted to creating multiple copies instead of the old-school single-copy mode.
Many users find this difficult at first but many appreciate the ability soon enough: the command can be cancelled by not clicking but my hitting or spacebar on the keyboard.

Starting in LT2008, you can actually turn off this ability with a new variable: COPYMODE by default is set to 0 (zero) and allows multiple copies. Change the setting to 1 (one) to get back classic single copy behavior. ◦

COPY command's Multiple preset

Export a Layout to a separate DWG file

This is a new feature in all 2008 versions of AutoCAD, including LT2008. You can use the Autodesk technology preview tool ExportLayout to export a selected layout to a separate DWG file, all the entities creates as modelspace entities in the new file.

ExportLayout is a free add-on you can getfrom Autodesk HERE, or from http://www.xanadu.cz/en/download.asp?file=ExportLayout

Read about the limitations of this freebie add-on HERE.

No, this add-on cannot be installed or used with in any version lower than AutoCAD/LT2008. ◦

SCALE command's hidden feature

Sometime you need to SCALE an object, or worse, a whole drawing from some unknown scale to at least a correct known dimension for one of it's sides or sections.
You could use DIST command to measure a known length, then do the math on a calculator and use SCALE command to get close enough to what it really needs to be.
Or you can just let SCALE command do it for you: the following tip is a feature of ALIGN command found in full AutoCAD but missing in LT.

1. First identify a length you know needs to be somethng else: this could be a rectangle's side or a door or a bolt.
2. Start SCALE command, Select the entity or portion of the drawing, or the entire drawing if that's the case, that you want to scale.
3. When prompted for the Base Point, Select a point on the object(s) selected above.
4. Instead of typing a scale factor, Type R (Reference) and select both ends of the dimension you want to correct (having running osnaps is best).
5. Type in the new length that you want, or if you are simply trying to match a dimension on screen, Type P (Points) and click on either end of the destination dimension you are trying to match.
6. Your entity(s) will now scale.

ROTATE command also has a Reference feature that works the same way, a great tool when you need to rotate an entity or entities to align with another angled object easily. Explore the topic in LT's Help.

Extra tip with both the above commands: check out the COPY option inside each, the action is applied to a copy but leaves the original intact.

Track Plotting from AutoCAD/LT for FREE

Here ia a tip that will make you popular with you billing folks, plot tracking: LT offers a free and simple way to track each plot you do, whether an image (pdf, dwf etc.) or to your printer, or plotter. And every AutoCAD/LT seat can write to the same simgle file too.

1. Go to the Plot and Publish tab in OPTIONS command. Click Automatically save plot and publish log, and select the Save one continuous plot log button.
   
2. After enabling the feature, go to the Files tab in OPTIONS command, and find Plot and Publish Log Location: change the path to a shared directory all your AutoCAD/LT seats can access, then Click OK.
   
3. AutoCAD will create a CSV (comma separated) file in that location. Each time someone sends a new plot it will be appended with the information about that plot. Open the CSV file with MSExcel or similar program to sort the file and generate a billing report for all your plotting.

OPEN command and options

1. When you start OPEN command, a pop-up appears that shows you the current folder and highlights the current file you have open along with the list of other files and folders. If you've lost that ability to display the highlight of the current file, it's because you've changed (or never set) Windows Explorer properly in Windows.
   In Windows Explorer, Click on Tools pulldown menu, Select Folder Options, Click on the View tab, Scroll down the list and uncheck the box labeled Hide Extensions for known file types.


2. You start OPEN command, and all you get is the command line asking you to type the full length address location and file name.
   To fix, change the setting of FILEDIA variable, explained in HELP in LT.


3. You start OPEN command and nothing happens: LT acts like the command is running, but you have nothing on screen. You are able to cancel the command.
   Your pop-up may be off screen: start OPEN command, on the keyboard use the combination of ALT+SHIFT+M then use the arrow keys on your keyboard to nudge it back to view (this is a Windows feature, you can use it to recover any lost pop-up in LT or other programs).
   You can also change the resolution of your monitor to lower settings, the layer manager will show up, move it to be centered, then change resolution back.
   If neither works, a reinstall of LT usually fixes it too.


4. If you regularly go to certain folders while using LT, you can add those folders to the left side of the OPEN command pop-up Window. Simply right-click over the area and explore the choices presented. See image below:
   
5. If you used VIEW command in your DWG files to save various views, OPEN command will let you open you file at that saved view (if you know what is it's name): this would be very useful if you turned on VIEW command's feature of controlling/setting layers. See Image below:
   
6. You can use OPEN command to open a DWG file, a DXF file and your save DWT Template file(s): with the last option, the folder where you store your Template files is automatically accessed, this is identified in Options command>Files tab section. See image below:
   
7. You can use the OPEN command's pop-up window to do regular Windows Explorer type functions, like renaming files, moving and deleting files, creating new folders, renaming folders and more.

LT on an Apple/MAC

You can run AutoCAD/LT on an Apple PC/MAC, you just need to buy more software and your Apple device must be on the higher end with 2Gig Ram to function at a reasonable pace (no blue-light special unless you are a very casual user).

There are two methods, one is to run Windows/AutoCAD in a "virtual window" on a Mac, ideal because you have access to and are in your Apple Operating System and applications at the same time, or you can reboot and run only Windows/AutoCAD on your apple hardware (what's the point of that I'm not sure).

This first image is running Windows in the Parallels Virtual Window, Windows desktop in a window on the MAC desktop (VMware is another option you can buy):
This screenshot is of Parallels in action. This one is in "coherence" mode, where the Windows dialogs all look like Apple's windows:
Here is a video on YouTube showing AutoCAD on a MAC:
http://www.youtube.com/watch?v=bb4MHp6_B-A

Bootcamp is a freebie from Apple but you must buy Windows OS and be prepared for a lengthy install and update process from Microsoft. This is nothing more than a glorified dual-boot loader where you are cut-off from Apple content until you re-boot the PC. A waste of time for any serious Apple user craving the full Apple experience. ◦

Understanding LT's many versions

Every so many versions, or version, AutoCAD/LT, Autodesk changes the file format of the DWG file. They also happen to change the DXF file format at the same time, a point often missed.

The following is a summary description of the many versions and what file formats they create:
AutoCAD/LT2007 and 2008 create R2007 DWG/DXF files.
AutoCAD/LT2004, 2005 and 2006 create R2004 DWG/DXF files.
AutoCAD/LT2000, 2000i and 2002 create R2000 DWG/DXF files.
AutoCAD LT97 and 98 create R14 DWG/DXF files.
AutoCAD LT95 create R13 DWG/DXF files.
AutoCAD LT V1 and V2 create R11/R12 DWG/DXF files.

Customizing LT's screen menu and toolbars

Since LT2006 customizing the toolbars, but especially the screen menu (pulldowns, right-clicks and more) has moved away from the realm of the CAD Manager and is mor easily available to the individual user.

CUI command launches you into the customizing window that let's you change almost everything you see on screen in LT. The following free tutorials are LT2006 specific but the majority still applies to LT2007 and LT2008:

LT cursor movement not smooth

The LT cursor no longer moves smoothly across the screen, it appears to jump and stutter and makes selection of entities and drafting quite difficult.

Tap the F9 key on your keyboard once and see if that helps: you may have turned on SNAP, explained in Help in LT if you don't know what that is.

Clean your mouse, especially if it's the older roller-ball type (or roller-ball trackball): and clean the roller guides too, build-up can also exhibit such behavior.

Replace the mouse and/or uninstall the mouse driver and let Windows run it to see if the problem goes away. ◦

LT locks up while using Trim, Extend or Hatch....

Or worse, LT crashes.
First, rule out the problem is the file by running RECOVER command (instead of OPEN) or AUDIT command if you are already in the file (remember to answer Yes to fix any errors found).
Another fix you can try is to turn off video card hardware acceleration in Windows: In WindowsXP for example, this is found in Control Panel> Appearance and Themes> Display> Settings Tab> Advanced Button> Troubleshoot Tab> Hardware Acceleration slider:

Abbreviations for LT commands

You would like to abbreviate commands such as Layer, Chprop, AI_MOLC and more with simpler one, two or three letters for quicker typing or macro writing.

These are called Aliases, and you can create them by editing LT's PGP file and adding or deleting what you need as you need it. To access the file, click on LT's Tools Pulldown Menu, Customize selection, Edit Program Parameters.
You will be presented with a new pop-up, scroll down and match exactly the format to add your own abbreviations/Aliases:
When you are done, save and close this file. At the LT command line, type REINIT, select PGP File from the new pop-up, then click OK: this reloads the PGP file you just edited. Your changes are now available for use.

PDF file creation from LT

You need to send a PDF file of your AutoCAD/LT DWG file to a recipient not interested in any other format, and your version of LT does not have a built-in PDF driver in the PLOT command or you prefer something better than the one built-in.

All you need is a PDF driver installed in Windows to PLOT to in AutoCAD, as well as the side perk of being able to Print to it from other programs like MSWord or MSExcel etc. to create PDF files too.

Free PDF drivers that work just fine in WindowsXP or higher are available through any internet search like this one, just click HERE.
If you have a problem with free, almost all of the vendors at the above link will sell you more advanced versions with more features and abilities. ◦

Insert a Raster Image File in LT

So you have this logo, or background picture, you want to insert in your DWG file: unlike full AutoCAD though, you cannot Imageattach the file as the command does not exist in LT.

Simply open the Image file in another program/viewer, Select the entire image inside that program (if you cannot, you need another program/viewer application), then use Windows Copy/Paste ability to paste the image in LT.

For Raster Image files like JPEG or PNG or GIF, you can use Windows' own Paint program to do this. Make sure you do not insert the image on a layer set to no-plot.

Example: Open Windows Paint, using the File Pulldown menu in that program, open your raster image file. In the Edit Pulldown menu, use Select All to select the entire Image, then select Copy from the same pulldown menu.
Click over to LT, Select the Edit pulldown menu, Select Paste Special... (or type PASTESPEC) and select any Image or Picture selection that best meets your need, and continue with image placement.

The above method also works for PDFs (using any PDF Viewer with selection features similar to Windows Paint described above), TIFFs, Word/Excel and so many other programs. You are only limited by your imagination, the 'other' program's selection methods, and your choices of PASTESPEC command's pop-up. ◦

Insert a Raster Image File in LT

Setting a Viewport's Scale in a Layout

You correctly draw everything at 1:1 scale in Modelspace. You have a Layout set with your titleblock, and a viewport(s) showing your drawing in modelspace. You need to set the scale to that viewport to plot the layout.

Open the Viewports toolbar (see previous posting here), select the viewport, then use the Viewports toolbar's pulldown menu to select a predefined scale. If needed, you can resize the viewport to better fit your view, and double-click inside the viewport to pan your view inside the viewport (be careful not to zoom, this will remove your viewport scale).

Don't forget to right-click the viewport and lock it so that the scale is never changed accidentally.

Cannot Fillet and more: lines are non coplanar errors

You cannot Fillet, Trim, Extend, Chamfer or Hatch in a file, LT reports that the lines you select are "non coplanar".
LT is still AutoCAD, a 3D program that has a Z height elevation: those 2D commands require your lines to all be on the same Z height, ideally set to O (zero).

Create a new toolbar button on a toolbar (preferably a custom toolbar on your own), and add the following macro (ideally just cut and paste from here, watch out for word wrap):

^C^C_UCS;;_move _all;;0,0,1e99;;_move _all;;0,0,-1e99;;_chprop;_all;;_thickness;0;;^M;

Now click on the toolbar button you just created, and select the entities in question (or your entire drawing if needed). Make sure your UCS is set to World. This routine will not convert 3D objects in your file to 2D entities. ◦

Cannot Fillet and more: lines are non coplanar errors

Modelspace background color

While in LT, go to the Tools pulldown menu, select Options, on the pop-up that appears select the Display tab, in the Window Elements section click on the Colors button, select Modelspace, select Background color (older versions only gie you the one choice), select color, then your choice.

Notice that you can change other colors of other display entities and areas there, spend a little time and adjust all items to meet your visual needs.

◦

Turn on a Toolbar

Right-click on any toolbar, and a list of all available toolbars appears: you will see a check mark next to each one that is on. Select the one(s) you want to turn on, when it appears on screen, just move it to where you need it.

If you know the name of the toolbar, you can try using the -TOOLBAR command (note the dash): just type it at the command line and explore the options. You can also use this command to relocate a toolbar to mid-screen if for whatever reason you lost track of it: type F for float, and when prompted for position type 300,300 and that should place it in your drawing area to relocated. Explore this command in more depth in HELP in LT.
