pkad,
We don't explicitly support any particular CAD/CAM packages. However, the specific functionality you are looking for is referred to as UserCode blocks, SystemBuild's parallel to S-Blocks. You can learn more in Chapter 14 of this
SystemBuild user's guide.If your CAD/CAM package can export the appropriate C code, then chances are you can get the code to work with UserCode blocks.
Hope this helps!
