Hi Allan, it's a little hard for me to understand what's going on there in your last post.

Is Houdini not able to read in some parts of the IGES file? You mention something about a piece missing?

Can you please post the actual IGES file here or e-mail it to me at moi@moi3d.com so I can test it with some other programs? That will let me figure out whether there may be something wrong with the IGES file, or if it is a problem with Houdini's importer.


But it is most likely a problem with Houdini's importer though, that probably has not really had a whole lot of attention on it from the Houdini developers. Houdini is just not really used that often in combination with CAD programs.

Reading IGES files is a pretty complex area so it is easy for there to be bugs in their handling if it is not much of a focus area for the application.


Probably you will get better results in exporting to polygons in OBJ format and reading that into Houdini instead of IGES files.
