CCAD's AutoCAD Add-on Programs Downloads
Feel free to download any or all of our free trials! 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. Once the download is finished, find the zip file on your computer, double click the .exe file and follow the instructions on the installation screens.
Attention Windows7 users: If you get a Program Compatibility Assistant pop-up window questioning whether or not the program installed correctly, please click the Cancel button. This is known issue with the installer program only and will not affect the application.
Please make sure to continue with the second part of the installation, which will pop up in a text file.
Please review our installation instructions video prior to installation.
These add-ons DO NOT work with AutoCAD LT. AutoCAD LT does not support the programming language used to develop these add-ons. The only exception is NCAD, which is an application that does not use a programming language.
