Mechanism: parts detatching from moving b

[scottydog]

I have a problem with parts not staying attatched to moving bodies. I have a mechanism and am bringing additional parts in (nuts bolts etc) to fix them on to the moving bodies. When I run the mechanism, the attatched components don't move. When I re-edit the definition of those constraints )place constraints on features of a part in the moving body) the constraints are still shown as being there, but but instead of "fully constrained" the mesage is "constraints invalid". Can someone tell me what I'm doing wrong here?


Thanks

your assembly structure is wrong.


If you can attach your files or send me the files I will fix it for you.

I've realized what my error was. I was using a saved analysis run which was created before the parts were added. By recreating the analysis after the parts were added the problem was solved.
