How do I convert STL and OBJ models to STP/STEP/IGS formats?

[ralphzoontjens]

STEP and IGES are common file formats used by manufacturing facilities for years. Together with DXF they are more or less the industry standard. They describe geometry in terms of rich definitions so the original smooth surfaces can be maintained rather than chopped up as in mesh formats like STL, PLY and OBJ. IGES is maintained by ANSI and STEP by ISO. The latter is a more recent format so I prefer STP. Some manufacturers will accept your mesh models though. If you want, I can convert these for you.
