Inventor Fusion does not currently support persistent sketch constraints. It's part of the whole "non-parametric modeling" philosophy.
Fusion will infer constraints and dimensions when geometry is selected, and the dimensions can be edited to affect the geometry. However, those are discarded when the geometry is deselected.
In your opinion, is this lack of dimensions and constraints a serious limitation to workflows, even in a "direct modeling/non-parametric" modeler? We are looking for honest feedback in this area, and we appreciate your questions and comments.
