1 Answer

When dimensioning in a CATIA sketch, the constraints of position are always based on the 2 elements you select. The dimension can either be to a part's axis system, or to the sketch's H,V axis, or any other geometry.

The sketch H,V axis is often based on the part axis but not always, so you should not depend on that.
