Thanks... but this is the issue I'm having. I went back and blended using the parameters you suggested, but when I join them to a solid and export that solid, Alibre throws errors saying it's found "convexity points" in the model, and all of my modifications in Alibre fail.

I shelled the part in MOI, but there were nasty artifacts inside the part. Shelling outward (flip) seemed to smooth things out in MOI, but the export still had a bunch of errors preventing me from using it in Alibre.
