I have a bunch of fairly simple, relatively small 3D files that were created in various 3D modeling programs like ZBrush, Maya, and Blender, all of which have been successfully exported to STL and OBJ formats and 3D printed, but which now must be converted to IGES, or better, STEP format for further revision.
I'm having trouble finding someone who can do this for me. From what I understand, the models may not be "convertible," but may need to be rebuilt using a program like SW.
How can I find someone who can do this for me, and what should it cost? There are 6 models and they are not very complicated.
