Convert to STP, IGS, X-T file formats?

Hi! Currently I have a job, where the client said that he will need the models in STP or IGS or in X-T (?!) file format to be able to "print out" them as injection moulding tool. My question is, how could I convert the models to one of these file formats? I work with Max and Zbrush, but they don't have option to export in these formats.

    I forgot to mention that I can't ask the client, because he also have a client, and that guy will make the injection moulding tools, and I have contact only with the first guy that I mentioned. And he also don't know how could I export to these formats.

    I'm afraid you won't be able to convert them. STP or IGS are file formats for CAD drawings, where a mesh is defined by mathematical functions, like NURBS, so completely opposite of polygonal models in Max and Zbrush.

    You could ask if they could print out from .STL files, which are exportable from Max and they work great, and with a completed mesh in 3Ds Max you can do a STL Check Modifier, check for errors and you're ready to go (I printed a couple of objects from .STL files from Max, no issues).

    The other alternative to deliver .STP or .IGS would be to recreate the model in a CAD program, like Solidworks or Rhino, with NURBS. Also, you could import your poly objects in Rhino for instance, and convert to NURBS (each face will be transformed in a NURBS patch) but I'm pretty sure you'll have loads of issues with open meshes and overlapping parts).

    Omm thats really sad to hear. Recreating them isn't an option because these are sculpted highpoly character models. So I still hope I can do this somehow :poly122:. I looked around on the internet and I have found a few answer that is saying its possible, but they didn't really explained how. I'll try to convert with rhino, but if somebody know an alternative solution, I'm all ears.

    I searched more, and I found that FreeCAD can import obj, and can export both stp and igs so it looks like the problem is solved :)

    FreeCAD didn't worked, but I succesfully converted my polygonal mesh to NURBS with Rhino, and exported it as STP!

    Hey Obscura, this is an old post but just curious, how did you convert your mesh to NURBS in Rhino, I was almost able to get the conversion working but not quite.
