Hello,

Despite having Spaceclaim I'm not sure about G2/G3 fillets. I use VSR for Rhino for surfacing tasks and v3 out next month has filleting added. VSR just got bought up a few weeks ago by Autodesk and they've said they'll continue Rhino support but who knows if this will turn into another TSplines situation. After seeing a demo of the fillet functionality it's worth the price for that addition in my opinion.
