Does this the last workflow ?

The steps to convert:
1. Export from Blender in OBJ. (or from any subD modeler)
2. Convert from OBJ to VRML1, with Meshconv. (Command line for Windows) **
3. Start FreeShip, and import the VRML1.
4. Export the file to IGES (NURBS).
5. Start FreeCad and then open IGES file and export it, to IGES or other formats NURBS, Moi3d does not open the file exported by FreeShip.
