I’m finding that the extrusion feature only runs parallel with the plane being effected. So, if you’re doing a compound taper, you can apply a second angle to an existing angled plane. If there was a control for the degree of extrusion, facets -for example - would be easier to cut.
Also, subtractive measurements - in addition to cumulative measurements would be a great aid in the efficiency of fitting contoured pieces into existing designs.
Lastly - the controls need to show where you touch the object vs the middle or you can’t see your precise fit.
