For example
- non uniform scale tool at least for a face or planar shape I mean to be able to scale a planar face of an object
-improve loft surface with control points that can adjust the surface curves like in solidworks (now the only thing that can be adjusted is the twist)
-complex bodies maniplulation (it takes a lot of computing time to extrude a simple face of a complex body) in my case the rivet of the wing were hard to do - surface modeling not ony solid modeling ( i think this is a hard one)
