Vanishing Constriants, and 'What Gives?"

“There is no such thing as a failed experiment, only experiments with unexpected outcomes”
Richard Buckminster Fuller


Since Inventor R2010 has been introduced, I sometimes see this bout of 'unexpected behavior' pop up.

Have you ever created a sketch, watch the constraints seemingly place, but after completing the sketch, suddenly had your sketch move around again as if the constraints never existed?

It's almost always caused by the inadvertent turning off of constraint persistence. Fixing it is really simple.

Of course all you have to do is know where to look.

See the attached video for a fix.

Enjoy!

  1. Yeah this question pops up more than it should. I suggested to ADSK to have it moved to the Expanded Panel for the next release since it seems prone to be selected by mistake far too often due to its proximity to the Constraints. Great Video!

  2. Thanks for the kind words, Mark!

    That one definitely seems to get folks. Especially when the constraints APPEAR to go in just fine.
