hi ycarry,

this part is indeed not 100% "clean"... the bevel around the quadpart is an joined surface....
the round bevel is part of the solid mainbody... but it renders absolutly ok.

i have sometimes "problems" to get the right fillet...
but with carefull placement of solids i solve the most cases.

i round near all egdes where its possible, even with very small amounts (0,01 cm)
bcause in real life, there are no hardedges (maybe on a knife:-))
