Our engineering dept recently upgraded from AutoDesk Inventor 2008 to 2010 and now the .STL files they send us for rendering are blown apart. We are a cabinet shop and the cabinet bases come in fine, but any drawers or doors come in blown apart and off axis. Apparently the components are losing their constraints. Everything worked fine while using 2008, so I'm thinking AutoDesk changed some setting with their exporter. Any help or insight would be much appreciated.

Hm, STL is such a simple format that I doubt that the importer is causing that.

Can you post a sample?

Cheers,

Here is a screen shot of what I now get after the Inventor 2010 upgrade. It appears as if assemblies are being treated different. This cabinet has a door and drawer and they floating out in space all broken up. Our resident AutoDesk guy is looking into the issue to see if it is on their end.

Yeah, that certainly looks like an export issue.

AutoDesk forgot to convert from local coordinate system to world coordinate system before exporting to the STL files.

You might try importing the stl into Accutrans ($20 program):

Then export out to lwo.

AccuTrans can not fix the problem as the information needed to convert from the local to the world coordinate system is not saved to the STL file.

AutoDesk has to fix their export module.

Or AutoDesk have added a custom extension to the STL format...

Would this be the case with dxf export as well?

Thanks guys for all your suggestions and ideas. I got in this morning and our resident AutoDesk guy applied a hot-fix from AutoDesk to our Inventor installs and everything is working fine now. So it definitely was an issue on their end.
