The two primary commands for filleting surfaces in Rhino are:

FilletEdge:

• Creates a tangent surface between multiple polysurface edges (joined) with optional varying radius values, trims the original faces, and joins the resulting surfaces together.
• Is not limited to just two surfaces
• Can fill in corners between adjacent fillets
• Is limited to exactly three surfaces meeting at a point
• The radiuses used can not be so large that they overlap each other and completely consume any surface they are following.

FilletSrf:

• Creates a tangent surface between two surface edges (joined or not) with a constant radius, and optionally trims and/or extends the original surfaces.
• Works on exactly two surfaces at a time
• Does not fill in corners between adjacent fillets

What if they don’t work?

Mitch's First Challenge
	Here's an example sent in by Mitch Heynick. Mitch writes: Fillet all vertical edges plus the base with a radius of 10. Fillet the horizontal inside edges near the top at 5. --Mitch

Mitch's Second Challenge
	Here's another example sent in by Mitch Heynick. I'll admit, this one stumped me but Pascal figured it out. Mitch writes: Fillet all the surfaces except bottom with a constant radius of 5. --Mitch
