AutoCAD Add-on Free Trials

AutoCAD Add-on Free Trials

Want to try the Demo Versions of our AutoCAD Add-on Software?

Sizes are limited in the demos, otherwise all features are available. Please visit our Software FAQ page for answers to typical installation issues.

These add-ons DO NOT work with AutoCAD LT, because AutoCAD LT does not support AutoLISP, the language used to write our Software Add-ons.

Instructions – please read carefully!

*These steps apply to a computer with the Windows 10 operating system. If you have a different operating system or have an application like WinZip installed the process will vary somewhat.

  1. When you click on the Free Trial links below, a dialog box will pop up asking if you’d like to open or save the file. We recommend that you SAVE the file to your desktop or other folder (please make a note of the location of the zip file)
  2. Find the zip file you downloaded to your computer
  3. Place your cursor (pointer) over the file
  4. Right-click and select Extract All…
  5. Click in the box below Files will be extracted to this folder:
  6. Type C:\CCAD Add ons
  7. Remove the check mark from Show extracted files when complete
  8. Choose the Extract button

Note: You must extract the files from the zip file as AutoCAD will not open files from a zip file.
