Capping Holes

Can someone help me figure out how to cap a hole. I have read Javier Garcia's tuturial on capping holes and I'm of the opinion that there has got to be an easier way in XSI version 2 to this, and that doesn't involve so many steps. Anyways, what I have is a curve in the shape of a cresent moon, drawn using the Nurbs drawing tool. It has an extrusion of 1 unit applied to it and it has a hole right through the center. Where in XSI version 2 is there a command that can cap the bottom and top faces of my cresent moon extrusion? Moreover, is it possible to apply a bevel to my cresent moon shape after I cap the holes? If anyone can help me out I would really appreciate it. Thanks in advance.

after you have created the curve, make sure tis closed curve. the go to Create -> Polymesh -> curves to mesh, after that, the property editor pops up, go to the extrude and bevel tab to set your options there.
