I have a relatively simple sketch with a circular pattern for which I have a strange behaviour.

The angle is related to the number of patterns (called here NbDents - number of teeth). When I decrease the number of patterns, the sketch reconstructs correctly and I get 8 teeth :

But if I now increase the number of teeth, I get something weird that cannot reconstruct. I haven't been able to find out where this comes from. Maybe from the order by which the relations are re-build during reconstruction… Any help would be greatly appreciated.

Christian,

Personally, I would stick with using the Feature Pattern rather than the Sketch Pattern. Feature Patterns seem to be faster, more robust, and easier to understand or work with. I think you have found another example from the 1001 ways that Sketch Patterns can go wrong.
