I'm sorry for this n00bish question, but I'm trying to work through the tuts in Maya Character Animation, 2nd ed., and I've run into a problem. In Chapter 3, there is a walk through in modeling a head. I got through Step 1 (creating the outline of the face via the create polygon tool and extruded the face), but now in Step 2 when I click Modify->Convert->Polygon to Subdiv, it keeps saying: Error: Select a polygon or a NURBS surface for which you want to create a subdivision surface. The thing is though is that well, I am selected the object. I use the select tool to drag around the entire object to get every selected and it still gives me this error? It must be something stupidly obvious that I'm missing. Could somebody possibly clue me in?
