Hi,

Trying to do a motion analysis on an assembly. Ive got the motion analysis working and have managed to calculate stress simulations for several parts. However i cannot do this for some of the parts in the assembly. In the 'Simulation Setup' window it just wont let me sellect the part i want. Any ideas as to why this is?

Probably a simple answer but im new to motion analysis!

Cheers

EDIT: Any help will be appreciated. Am working to a tight university deadline...
