While I am finishing my archtop, I have started on an F5 mandolin.
I want to do the scroll and also get the surface thickness correct.
Despite a lot of comments on BobCAD, I find it good enough for me to do what I want (to date).
Occassional problems such as falling over, but just remember to save often.

Surface to date:
Still need to work out what happens at the neck and scroll, and also what happens at the triangular bits (are they curved, flat etc).
