in case you have the font installed use the text tool from maya. this creates an extruded nurbsGeometry by just typing the text. otherwise you might want to look under surfaces/nurbs I think and test with the extrudeTool. you need a profileCurve and a path curve for that. or try the bevelOperation on your curveLetters. easiest way tho is with the textTool. I think it can be found under Modify. cant remember right. havenĀ“t used it in a while and no maya here. but the tool is in one of the basic dropDown menus.
everything starts and ends in the right place at the right time.
