Hello,
I have been using Viacad Pro v10 for some time now and was exited to see Constraints in v11, which made me upgrade immediately. So far, it has been a nice feature and very helpful!!

In a current project however, there seems to be a bug which I cannot track down...

When changing something, or resolving links, I keep getting the message "Unable to resolve associative changes. Press Undo to restore model previous state or Suppress invalid features". Since I don't know when this first happened, I cannot suppress or delete the features causing this (Undo won't help either of course) - I don't know whether this is caused by a feature or by a constraint at all.

Is there a way to track this down or see what's wrong at all? Also this error is preventing any new constraints to be created.

Sidenot: there are two constraints dimensions which should have been deleted already (since they are unused).

Thanks a lot in advance for any help!!

Best regards
Sebastian

Thanks a lot for the hint. Actually there were a lot of red "R", but mainly on the constraints.

I now deleted anything not needed anymore and could strip it down to a problem with a solid, which to my surprise did not show any R in the concept explorer. Now new constraints get accepted again.

Regards
Sebastian
