I'm struggling a bit with 3D surfaces, specifically Bezier surfaces. I need to create a Bezier surface in Autocad (2006). Whilst I understand the theory and maths behind Bezier curves I can't find any help for actually making a simple Bezier surface/patch (16 points).
At the moment the best I can come up with is just inputting a 4x4 3D mesh, setting the SURFTYPE to Bezier ( and inputting the points which can't be right?? Any help much appreciated.
