Hi, Anyone can help me? I have a data file about my face. It is a txt file which only includes X Y Z position data. I can import it into AUTOCAD and see theface. However, It is only a point cloud. I want to convert it into surface and then a solid model. This is interesting because once I get the solid model, I can export a stl file for Rapid prototyping and make something interesting. Does anyone know how to convert point cloud to solid object in AUTOCAD? Thank you very much.
