Features Keep "Detaching" from CAD model

[[Ia...]]

I have a few programs where I need to use CAD Model Comparison literally every time I open it to make everything look pretty. Is this common? And if so, does anyone have a solution?

Not a big deal, just annoying.

I've gone on record previously and declared CAD model comparison as the most worthless tool in all of CMM'dom.
It does nothing but make a surface change color, but if you swap a cad model and something about that new surface changes, the comparison WILL NOT change the feature nominals to correspond to the new surface (meaning if a diameter of a shaft changes, or the xyz location of a sphere changes by a couple thou, comparison might find the surface and highlight it, but the feature nominals will not change)
Comparison also is hit or miss weather it will even find a new surface, even if it is 100% identical to the old model.

On the other hand, i think the PCD Binocular tool is possibly the best tool in all of CMM'dom. after swapping a model, open a feature and click the tool and the feature will snap to the new surface and all the xyz, and vectors will change normal to the new surface.

Yes that is Calypso for you.
I have not found a stable version of Calypso that doesn't do that from time to time.
