Is there anybody know why Collision Detection grey out, only standard drag available when I try to do some collision test to see the stem is able to go through. Tks.
I think the assemblies forum might be a better one for your question.
Also it might be worth posting what you see in solidworks, I just see the parts. Is it a part? Assy? Can you drag it? Version and sp that you are using? Does it work for other models?
