Thoguht I'd tackle another Rhine tutorial (found here: http://www.rhino3dhelp.com/tutorials/modeling-usb-connector/ ), I ran into a stumbling block when trying to add fillets to the shape. Here's where I got to:



When I select the edges for the shape (it's all one piece that I joined) and try and fillet, nothing happens. If I pick just a few edges I can get a fillet, but not if it's a complete loop. I've no doubt there's something obvious I'm missing but searching through the forums has turned anything up yet (at least so far). I've attached the file in case that helps.
