Changing Material Breaks Constraint or Host Cut

[chughes]

I have a couple of families that, when I change the material, create a 'Constraints not satisfied' condition or a 'Can't cut instance' condition.

Any ideas as to why a material change (one paint color to a different paint color) would create this issue?

Thanks.

mmm?  Well, just theorizing: if elements that have the same material are joined, then visible edge between them is removed. Right? So, maybe by changing the material you are effecting those join conditions.  Out of curiosity, does the error message come with an "<Expand>". If so, what does it say?
