Jon:

Rather than slamming 3d printing, how about an assist in
designing/processing the parts for printing?

Most of the posters have a knowledge of cad, and can create
a 3d wire form of an object. and have access to a cad
program.

What hints would you care to give to the group for creating
3d surfaces from a wire frame model, particularly compound
curved surfaces and inside corner radii, so these are
"manifold" and can be processed through a "slicer" program
to generate the FFF g-code file for 3d printing?

Do you know of any [free] VBA or AutoLISP macros or add-ons
to "skin" a DXF/IGES wire frame?
