Here is the problem. I have seen this on a number of drawings now, so I need to find a solution. The problem can not be replicated in new parts consistently though, so it is odd.
Issue: changing or modifying a GD&T tolerance block in a part or assembly removes the GD&T block AND the dimension it was attached to from the drawing.
Basic workflow to create the issue I see:
Create part with dimensions, attach GD&T in part to appropriate dimensions in sketches
Show model annotations on drawing to put proper dimension and GD&T block on drawing
Edit GD&T block to change a value
Dimension and GD&T block disappears from drawing and no longer shows up with show model annotations, and there is absolutely no way to get it back that I have found.
Because of this, I am forced to create dimensions in the drawing itself to get around this issue. Sometimes I have to create a completely new part/drawing and start over when I absolutely must fix it correctly.
any ideas?
Has shown up on Creo 2 M60, M130 and M200
