How to convert a mesh to a STEP file

Question

I want to convert a mesh (*.obj, *.stl) to a step file. Is this possible? I converted each triangle to a face and the result step file was too large to use. Is there any method to convert mesh triangles to NURBS?

Answer 1

No, it is not possible. There is no way to convert triangles to NURBS surfaces for a number of reasons. Some software tools, with a good amount of manual work, can accomplish this task but it is not a file conversion operation as you requested.
