Reset AutoCAD/LT without losing customizations

Sometimes you just need to reset AutoCAD/LT. It happens. Problem is, you lose all those menu customizations and/or workspace you spent time creating, moving and rearranging.

It is fairly painless to back up your customizations before resetting:

1. Windows START button, click on All Programs, then Autodesk, then AutoCAD LT 2015 (or lower), then Migrate custom settings, select Export AutoCAD LT 2015 settings.
2. Click the EXPORT button.
3. In the Export custom settings dialog box, select a location (like your desktop) to save the ZIP file created by the program.
4. Now you are ready to Reset AutoCAD to Defaults: go to Windows START button>All Programs>Autodesk>AutoCAD  LT 2015>Reset Settings to Default and it will reset and restart AutoCAD LT. 
5. Ensure the gremlins you wanted fixed are gone.
6. Exit AutoCAD/LT, then go to START>All Programs>Autodesk>AutoCAD LT 2015>Migrate custom settings>Import AutoCAD LT 2015 settings to bring your customizations back in.

Using Windows 8? Upgrade to Win8.1 first, then grab the free Start Button add-on and get back that useful functionality. ◦

AutoCAD LT for Mac: Tips

Specifying a different TEMP folder for AutoCAD/LT

AutoCAD/LT defaults to your Windows Log-in Temp folder location for many items (including your Autosave files) it needs to run every time you use the program. While this is convenient to program for the, it becomes difficult for you the end user to find these items when you need them the most.

To access your default Windows TEMP folder, you can either use Windows Explorer to go to the following folder:
C:\Users\YourNameHere\appdata\local\temp\
or Click Start menu (Windows) then Run: In the Run dialog box, enter %TEMP% and click OK.

You can however set up AutoCAD/LT to use any other folder you may have or wish to create: this can me one single folder on your local PC that you can access quickly (in the screenshot example below I use a folder called TEMP located on my computer's C primary drive).

Or you can create multiple folders, one for each of the five categories in the screenshot above, or just one additional folder for your Autosave files for example. After you create one or ore of these folders in Windows Explorer, open OPTIONS command's FILES tab, select the entry you wish to change, select the folder name, tap the BROWSE button and browse to the new folder to select it.Just follow the sequence of numbers in the screenshot below.

You now can easily find your temp files and SV$ extention Autosave files quickly. ◦

Specifying a different TEMP folder for AutoCAD/LT

Calling External Applications from AutoCAD/LT

While AutoCAD/LT is running, you can invoke (start) other programs or utilities such Windows system commands, utilities, and applications: the coding is simple and coded in the same file that AutoCAD/LT uses to read those command shortcuts we all use instead of typing full command names, the ACADLT.PGP file (for AutoCAD users, it's the ACAD.PGP file).

You define external commands by specifying a command name to be used from the AutoCAD command prompt and an executable command string that is passed to the operating system. By default, defined in the acadlt.pgp file are three commands that work to call up a couple of the most common Windows based Applications. These commands are listed as follows.

EXPLORER - Launches a session of Windows Explorer
NOTEPAD - Launches a session of NotePad with file provided if one is given
PBRUSH - Launches a session Windows Paint (or Paintbrush).

The coding structure inside the PGP for these external commands are as follows:

,[],,[*],

Examples of external commands for Windows built into LT by default:
EXPLORER,  START EXPLORER, 1,,
NOTEPAD,   START NOTEPAD,  1,,

PBRUSH,    START PBRUSH,   1,,

What does all ths coding mean?

• The first part represents the command name that you type in AutoCAD to execute the line of code.Feel free to abbreviate any of these to your preference, we show them with full names for clarity of this article.
• The second part calls a defined command from earlier in the Acad.pgp file.  This command is used to launch an executable that is registered on the current system (basically, how Windows calls the command).
• The third part is used to allocate memory.  This field is used maintains compatibility with previous versions of AutoCAD.  Typically the number zero is present.
• The fourth part is used to display a prompt at the AutoCAD Command Line.  This field is optional to use and the response to this prompt is appended to the string supplied in the executable field. If the first character of the prompt field is an asterisk (*), the response can contain spaces and the user must press ENTER to terminate it.
• The fifth part is an optional bit-coded parameter.  These codes can be added together in order to reach the desired results.

Here are examples of external commands from Windows we modified and added to LT. In these first to examples, we added additional prompts at the command line to prompt the user:

EXPLORER,  START EXPLORER, 1,*Directory to Start in: ,

NOTEPAD,   START NOTEPAD,  1,*File to edit: ,

 

Other examples of external programs to call from inside LT at the command line, or a menu/screen button:

EXCEL,    START EXCEL,   1,,

WORD,    START WINWORD,   1,,

POWERPOINT,    START POWERPNT,   1,,

WORDPAD,    START WRITE,   1,,

OUTLOOK,    START OUTLOOK,   1,,

 

What external programs would you find useful to call from inside LT?

AutoCAD Tips that work in LT: Part 2

Customizing LT: start with the Ribbon

During a slow work week recently, I had the opportunity to tackle a long list of to-do items in the office, including Network and desktop software updates for all of my colleagues' PCs and laptops.
I also took up the task of revamping our LT and AutoCAD screen Ribbon menus to create a more uniform appearance, as well as rewriting more common command shortcuts keys. For reasons more to do with legacy routines than anything else, both AutoCAD versions have had differing appearances and slightly different shortcuts abbreviations (mostly Lisp shortcuts in full AutoCAD).

Below are screenshots of LT: since we have a mix of LT2011 and LT2012 (as well as AutoCAD 2011 and 2012), I started with LT2011 for one simple reason. CUIx menu files are by design from Autodesk able to go up a version but they are not backwards compatible. So had I started with LT2012, I would have had to recreate the screen menu changes from scratch in LT2011. I sought out feedback from my coworkers on what they wanted to see, what they used often, and what things they wanted to do more with in order to spedd up their work day.

The approach to the redesign was simple: make the most used tools visible at the top of each panel, and less frequent tools are placed in the Panel's pulldown portion. Where possible, each tool is a smaller pulldown that offers more abilities to that command: for example, the LINE button on the first panel of the Home tab is a pulldown that also offers DLINE command, XLINE and RAY commands.

Here is version 1.0 1.1.

Home Tab

 Having moved the most frequently used commands up, and the less frequent commands down in each panel (see above, two views of the Home Tab), I also added a few more panels our users wanted: these include Osnaps (coded so the user can add or drop when clicked) and Group.

Insert Tab

Here I expanded many of the default Panels in this tab, and added available online libraries of blocks from manufacturers we use often.

View Tab

 In this tab I added several new Panels for Script files we use most often, Viewport Layer controls (yes, you can control viewport layers separate from modelspace layers), and enhanced the existing panels with some additional commands, variables and customizations.

Annotate Tab

This tab is set up for all things Annotation related: In addition to text and dimension tools, I added a panel for Notation blocks, Room numbers, and dimension overrides.

Custom Tab

In our field of Architecture, the LT users have few tools to work with that are native to LT: I have added custom routines over the years for adding doors/windows/sidelights (with wall breaks), ceiling grid routines and more. Now I just need to work on my icons to look less sloppy.

Output Tab

In addition to having more tools on display, I added a panel to simplify the built-in Export options available in LT for the users.

Manage Tab

This Tab is mostly dedicated to "fixing" a DWG file and I added new panels to adress exactly that need: Linetype Scales settings, Recovery, Purge, Variables settings, Variables toggles (on and off), as well as a few customizations to fix objects not residing at Z=0 elevations.

Online and Parametric Tabs

These are core tabs that I did not change: the ONLINE tab is available with no effort in LT2012, bur in LT2011 you must install this add-on to gain access to the excellent cloud service AutoCADWS.

Field testing went well with a few key employees in both full AutoCAD and LT. Their feedback resulted in the Versions 1.1 you now see above in the snapshots. In a future blog I will cover some of the basics of using the CUI command to customize the Ribbon to match your needs and requirements, but in the meantime I must finish migrating the above into LT2012 (and AutoCAD 2012). ◦

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.

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. ◦

F1 key reprogram to stop calling HELP

These directions will remap your F1 key in LT2006 or higher to act like theescape key: same concept should work for other F-keys too:

1. Right-click on a toolbar and select Customize... to open the CUI Editor.
2. In the upper left area, expand Keyboard Shortcuts and then Shortcut Keys.
3. Drag a command from the command list below into the Shortcut Keys (I used the first command .XY).
4. The command should now be in the Shortcut Keys area. This creates a new shortcut key with the same name as the command. Right-click on the new shortcut key and select Rename. Rename it to "F1 Remap" (no quotes).
5. In the properties area for the new shortcut key, Change the description to something else (or just delete the text there).
6. Change the macro to the following, which basically cancels any running command, you can add another command if you desire: ^C^C
7. In the Keys text area of the access heading, clickinside the text area to activate it and then press the button on the right with the three dots.
8. The shortcut keys dialogue box comes up. Place a cursor in the area called "Press new shortcut key:" and press the F1 Key on your keyboard. F1 should now appear in that box. Click on the Assign button. F1 should now appear in the Current Keys section. Click on OK.
9. Click on Apply in the CUI editor and then OK.

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.

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:

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.

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. ◦
