Hi Tom, unfortunately it's pretty common for fillets to be primarily done as circular cross sections rather than as G3 blended cross sections. I'm not sure right off the top of my head which other programs would be able to do that for you, you might look at SolidWorks or NX. Note that these are pretty expensive programs.


> Alternatively: is there an efficient way to do G3 fillets by hand, for instance with blending, on non-trivial objects?

It's difficult to do it by hand efficiently, particularly in handling corner juncture areas where multiple edges meet up.
