Hi. I know that my problem is possible to solve, but I don´t know how to do it. Can anyone help me, please? Imagine that I have a cloud point (points in 3D with no logic position) and I want to make a surface with those points through a system of triangulation. What I want to AUTOCAD do is to make triangles with those points in a way that the triangles don´t traverse themselves. Can I do that and how? Please and thanks in advance, Ervilha
