what is wrong with the standard interference detection in the program or are you trying to do this in a single part?
No. I'll try try to explain it in a better way.
A suspension of a car (let's focus just in a quarter suspension) is a multi body system that has several degrees of movement.
Once the CAD is done (assembly), I need to impose a position in the system (the center of the wheel is 40mm up from the top plane, for example) and then check if exist interferences. Since the suspension has various possible position (imposed by wheel travel, steering, static camber, static toe) checking for interferences in all these position is a time-wasting process. I wanted to automate this process but I need to know if it's possible to do.
I see where your at....and can see the time it takes to check for things that can be getting in the way...
Hopefully some of the maco guys will be able to help....
Or you could look up the guys at SOLIDBOX. I have seen some stuff that they have done on monster trucks...they may have a few ideas.
It's possible. Not sure I would invest the time to do it in a macro though,
