Hi Bill, in the STEP import library if it runs into some errors figuring out the joining information in there, it will just try to grab all the surfaces individually.

That's the main way to work on this kind of problem, at some point you'll probably find an area that may have some badly formed surfaces that may need to have some reconstruction.

Take note of the overall size of your model, then scale it up or down by 10, then do the seperate/join on it, to locate the problem area.

I now have files that are showing as solids. This is a major step forward. However, if I try to export to STEP, it still separates the surfaces individually. These are hundreds of surfaces in these models. Is there no way to make this work? If I have an MOI file that shows as a solid, is it going to show me the problems that are causing the export to STEP to fail?

Have you tried importing the STEP file into a different program? If you're exporting to STEP using MoI and then importing back into MoI also, it's difficult to know whether the separation is happening at export time or at import time.

No, there isn't anything built into the STEP exporter that would give back specific information like that.

Taking the way to perfection, thats how every piece of software should be. Great work there!

Has anyone tried the 3dm import function from Rhino to Solidworks on MOI 3dm files? Is this an option, because this is what I am trying to achieve by exporting to STEP.
Incidentally, Michael, the problem must be on export because the SolidWorks guy is opening the STEP files and getting individual surfaces.

If you have a "solid" in MoI and export the STEP file, what happens if you just import the STEP file "back into MoI" right after export?
If you export "IGES (surfaces)" then import to solidworks and attempt to Join, solidworks will have many options to show you problem areas. Or, you can attach your file here so it can be looked at. If it's proprietary or something, a private email to Michael can help to handle that.

Yeah, that's definitely worth trying - I'd recommend trying all of STEP, 3DM and IGES as well to see if one of those works better for your particular case.
Also it's very normal for IGES files to contain individual surfaces in them so most likely SolidWorks will go through a joining process itself if you use that format to transfer stuff over.
