View Full Version : Getting STEP or IGES files into Lightwave Mac

07-26-2015, 08:16 PM
OK, I am missing out seriously as I want to use a ton of objects off GrabCad but most of them are STEP or IGES file formats. I have searched high and low for some kind of converter so I can load them into Lightwave and have come up short.

So, does anyone know of a converter that I can use, a website that will convert them or any other way to get these formats into Lightwave?

Thanks in advance.

We had a project last year where we needed to get cad files into Lightwave. We ended up subscribing to 3DS Max for a month to convert the files. As I recall it was hard to find out how to unsubscribe when we were done. I had to ask Autodesk tech support how to do it as the unsubscribe option was very difficult to find.

I've used the open source Freecad to convert many CAD file formats to OBJ: http://www.freecadweb.org/

I've also used this online converter to go from STEP to STL (which LW 11.x+ can import): http://www.interop3d.com/apps/

Thanks for the links wesleycorgi ( especially http://www.interop3d.com/apps/ )

I'm using moi3d for direct convert to LW. It has great converter and adjusting settings. Not free but not too expensive either.

I use Rhino a great software to have for CAD conversion and Nurbs modeling, not free but really good. Otherwise search for a free CAD software that can export .obj files so you get the vertex normals also.

OK so as a trial by fire I tried a 210meg step file on both freecad and interop3d site. Freecad did seem to load the file and listed all the components but anything else failed. I just got a spinning beachball anytime I would make it active. Also the interop3d site just hangs. I thought it was taking a long time since it was a large file so I just left it running and went to the store and then lunch, came back and it was still doing nothing.

Rhino is currently $295 (sale price) but that is still a lot to just convert files. I will have to think about that one.

Try the trial version of Rhino, I think it will let you save/export 30 times.
