when you import a step/iges (or other solid bodies) file it would be great a feture that "recognizes" features (with respective sketches) on an imported solid body in a freecad part document.
Recognized features are the same as features that you create using freecad. You can edit the definition of recognized features to change their parameters. For features that are based on sketches, after you recognize the features, you can edit the sketches to change the geometry and or constraints of the features.
what do you think?
