This tutorial will show you about extrude command in Maya using CV curve in to make a NURBs surface. The extrusion is common command in Maya, 3d s max and AutoCAD for 2D and 3D software. The concept of extrusion is likely similar in both Maya and 3Ds max. The extrude command is applied in modeling either in polygon or NURBs. In polygonal modeling, we extrude the polygonal faces to give the model required shape. It change the look of your model completely, when you pick the polygonal primitives, they are in rough and simple shape. We can modify their shape by applying extrude and bevel command on it. In this part we are going to teach you about extrusion about curve, the curves are mostly used in NURBs modeling. In NURBs modeling, first of all the object structure is created with CV curve and then it is applied by extrude and bevel command. These commands are applied on face and edges respectively. If you want to create vehicle modeling, then NURBs modeling method will be proved very helpful in this matter. It will provide you good control vertices to control your vehicle modeling. This tutorial is just introduction of this concept of NURBs curve extrude in Maya.
