While I must say that this program is incredibly powerful for frame design, it's crippled by the fact that there is no means of adding custom tubes sizes from within the GUI. Making the issue even worse, the extension is missing some of the dimensions that are common to FSAE frames, such as 1.0"x0.095" tube. Since AFX is popular among teams that use Creo over Solidworks, I knew there had to be some way of adding the sizes I need. After a lot of rooting through the program's file structure, and tinkering with several files, I discovered a method for adding sizes, and I'd like to share it with everyone.

The download button you want is the gray one in the center that reads "Download this file".

Admittedly, this hosting service is crap, so feel free to rehost it anywhere you like.

Hope it helps! See you guys in Michigan, 2014!
