How do I convert STL and OBJ models to STP/STEP/IGS formats?
This is my first post on the forum in quite some time, so I'm looking forward to hearing what you all have to say.
I'm currently looking to mass produce plastic and rubber parts. I've been in contact with several facilities overseas who are all requesting that I send them my models as either STP/STEP or IGS files. Currently, the only versions I have are OBJ and STL.
I have two questions:
1) As you can probably guess: Is there software that can help with such a conversion? As of right now, I've tried Fusion360 and FreeCAD. Neither seem to work. Could that have something to do with a high polygon model? I'm actually relatively new to 3D modeling and printing (I know more about printing than modeling), so I'm not sure.
2) What exactly are STP/STEP and IGS models that seem to make them ideal for manufacturers? This is more just for my own knowledge and edification.
If anyone can offer ANY sort of help or advice, I'd be very grateful.
Very nice to meet all of you!
PS - I attached some images of some examples of the models I'm working with, and put them in a folder, here: https://app.box.com/s/5xcxjrbimkdko0q0dee7eof2bghaygcj

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. Send me a PM - Cheers, Ralph
