Introduction to the nurbs curve in blender 2.9 (Nurbs curve modeling)

By The Daily Show with CG

When designing with nurbs curves in blender 2.9, there are two types of the surface curve that you can use: tessellation or boundary representation. If your goal is to model something like chain link fences then I would recommend using a tesselated curve because it will give an interesting effect when rendered onto 3D objects; however if modeling parts for building purposes only where smoothness matters more than detail orientation could make sense by choosing boundingSurface instead since this type does not require any special treatments beyond setting thickness values along its lengthwise axis iurof.
