Inventor R11 Constraint Error

[imcjoek]

Hello,

A coworker of mine is having problems with his Inventor R11 software.

Ordinarily when an assembly is over-constrained, has constraints that conflict with each other, or geometry that is referenced by a constraint is deleted, an error box will appear in the top left stating the problem. Also the design doctor (Red Cross) button becomes available to highlight the problem.

This does not work properly on my coworkers machine. In the event that he makes errors in the constraints, the error never appears. Dragging any assembly components results in them snapping back instantly. Attempts to delete or suppress ANY constraints does nothing; no error, and no effect at all. The only way to repair the assembly is to open it on a different PC to delete the constraints. Once saved, he can resume work normally on his own machine.

In application options->Prompts menu we have set everything to "ALWAYS", so I don't see why the error does not appear. We have also tried uninstalling, wiping all traces of inventor (registry, folders, etc) and reinstalling. This did not fix the problem.

Has anyone encountered this problem? Autodesk folks have been less than helpful...

Thank you,
Joe K.

I had a similar type of problem, with assemblies 'jumping' around, all of a sudden, leaving pipework, including adaptive stuff, hanging in mid-air. I received no errors on the constraints which were obviously very much in error! I traced this to having multiple grounded assemblies in my top-level assembly. It might be worth him checking for such a situation.

I appreciate the response,

However in this instance it is a single assembly with perhaps 15 parts that is giving issues. It has happened with multiple assemblies of a similar nature. I have just checked one of them and he has only a single part grounded.

The part that really bugs me is that the assemblies work fine on my PC, but not on my co-workers.

Thanks again.

Could the problem be graphics card related? I say this because it seesm that the display is incorrect, but that IV can't see a problem with the constraints. Mind you, I'm guessing here!
