Nurbs Curves in 3Ds Max
One way of modeling in 3ds Max is with NURBS surfaces and curves. NURBS which stands for Non-Uniform rational B-Splines, is an industry standard for designing and modeling surfaces. Using polygons can make it more difficult to create complex curved surfaces.
Step 1: click on point curves tool.
Step 2: Pick one by one point after that pick start point for close.
