Collision detection in Creo Parametric

Collision detection in Creo Parametric

Collision detection in Creo Parametric

(OP)
Dear all, Another company does some engineering for us, using Creo parametric, the newest version.
In the STEP file we get, there are a few collisions and the engineer told us, that we have to find all of them manually, but I can hardly believe that.
Is it true that an additional software package is necessary to detect collisions within Creo?
How can collisions be etected with or without the additional software?
Thank you!

RE: Collision detection in Creo Parametric

I thought it was part of the basic license for assemblies, but PTC never makes a clear list of which commands are supported by which licenses. The function is called "Global Interference Check" under "Analysis Tools"

Depending on how parts are modeled the #1 cause is if threaded holes in nuts and other parts are modeled at the minor diameter and screws/bolts have their threads at the major diameter then every assembled thread pair will interfere, which is what threaded fasteners are to do. This can report many interferences. #2 is fillets under screw/bolt heads will interfere with nominally sized holes, so if those fillets are modeled that can also result in large numbers of small volumes of interference.
