STEP File format

Recommended Posts

VW does not support export as a STEP file. Anyone know of a work around? I need to export files for associate who uses Rhino on a PC. Thanks.

NNA does not see STEP as anything important. Well, it certainly does not help drafting services doing Colonial stairs and Texan windows in Oregon, so why bother.

It depends on what your associate wants to do. Rhino can read a .dwg file, it can also read an .iges file, which is probably the better choice.

I agree, an IGES file is the best approach. Tied for second would be dxf/dwg or 3DS file.

The trouble with IGES and dwg/dxf files is that when he opens them in Rhino, all the 3D elements are exploded. A cube, for example, is broken down into 6 separate planes. This requires lots of extra time to stitch everything back together for rendering. Don't ask why we have to use Rhino, long story that I don't have control over. Re; 3DS, I'll ask him again, but I'm pretty sure he said Rhino will not import 3DS files.

From the Rhino web site

IGES (Alias, Ashlar Vellum, AutoFORM, AutoShip, Breault, CADCEUS, CAMSoft, CATIA, Cosmos, Delcam, EdgeCAM, FastSurf, FastSHIP, Integrity Ware, IronCAD, LUSAS, Maya, MAX 3.0, MasterCAM, ME30, Mechanical Desktop, Microstation, NuGraf, OptiCAD, Pro/E, SDRC I-DEAS, Softimage, Solid Edge, SolidWorks, SUM3D, SURFCAM, TeKSoft, Unigraphics), NASA GridTool, Yamaha ESPRi, Tebis.

That's not to say any of these will give you what you need, but I hope something works out for you.

You can also export to a SAT file from VW.

An IGES shouldn't be exploding. You may want him to contact Rhino's TS to see if there are some settings he may be missing.

Katie, everything is converted to NURBS during translation - the only object type that Rhino deals with. So, just as in VW, when you convert an extrude to NURBS, you get a group of NURBS surfaces.

For rendering purposes, these will render like any other Rhino surface. I don't think it's reasonable to expect any better translation from one program to another when the one supports multiple object types, and the other doesn't.
