Visual notice of errors to geometric constraints 2

Example: I have two bodies in a part file, the top plate has a countersunk hole, the bottom plate has threaded holes constrained to the countersunk holes. During the design change the top plate holes are switched to counter bore holes and the counter bore holes are moved slightly. I did not consider the hole change would break the constraint between the two sets of holes, but they did and the threaded holes remained in the original location. It would be nice to have a flag pop up (like the feature info alert) in the part navigator letting the user know there is a possible problem in the sketch/feature to review.

Is there a setting to turn on a visual notice, such as informational flag in the Part Navigator that sketch constraints have been broken?

Thanks

If you have constraints between 2 bodies in a part file, I assume you are in an assembly file and are using assembly constraints. Are you using the 'hole series' feature to create the holes in both components? or are the holes created separately in each component?

This is not an assembly file, so this is not assembly constraints but feature geometric constraints. Not using hole series feature, and yes creating the holes separately in each body.

In this case, I'd try driving both sets of holes from the same geometry. For example, if you sketch 2 points to create holes in body1, re-use the same points to drive the holes in body2. You may need to project them to a different starting surface in body2, but it would be associative and the holes would update together even if the hole type is changed.

Yes that's a pretty good alternative, and I have done that before, sketching the points on the top surface and then projecting the points as needed. It works but it's sort of annoying (to me) to create 4 steps (sketch points, project points, create holes, create second group of holes) when only 2 are really needed.

Does that mean there is no ability to flag/identify problematic geometric constraints outside of the feature?
