cad feature list

sketches

• lines, arcs, no spline
• constraints (tangent, parallel, h,v,etc)

geometry

• create arbitrary plane from point+line normal. plane normal always faces same direction.
• extrude, cut extrude, boolean add (combine), subtract. no sweeps.

other features

• save face as dxf.
• fully parametric, with feature tree. adjust sketch dimension and whole model recomputes. (shows rebuild errors)
