Hi JD,

today I got a problem with the meshing of my scene. the following error message is created:

any idea, what's causing this and what I can do? SelBadObjects and ...-Ex didn't show anything.

Hi Kami,

Unfortunately, the nature of an SEHException is this: it is an exception thrown by low-level code (i.e. by a component underneath the plugin) which is not mapped to any specific .Net Exception. So all I can say about it is that something very bad is happening when the Maxwell SDK (this is where you see that the error started in an object named Cmaxwell), which the plugin is built on, attempts to create this particular mesh.

If I had this happen to me (I haven't), I would probably either try re-meshing the model using different parameters (in Rhino), or if that didn't help, I would manually export the geometry out to another file, change meshing parameters and the tolerance on the document (i.e. Document Properties > Units > Units and tolerances), and cause the objects to be re-meshed by Rhino.

Besides for those ideas, I would also try: window half the objects, and export an MXS using the plugin's Maxwell_RenderToMxs command with the RenderSelectedObjects option (same as a right-click on the 4th button in the Rendering toolbar). If the export is successful, I would use Rhino's Hide command on the object-selection, select another half of the remaining objects, and repeat this process. If you are able use this method to find a particular object which causes the problem, I would like to see it, to see if there is anything special about it which the plugin could be checking for.

Thanks,

JD

Hi JD

I isolated the mesh which caused the problem. It's a joined object of several meshes ... if I explode it, everything works fine.
It's just weird. I often got many problems, which the command SelBadObjectsEx doesn't find. Sometimes I can isolate the object with SelBadObjects and repair it myself... but then there are times where objects remain which can't be rendered.
Also, I know I rendered the same object before and didn't changed it since then. But somehow it got corrupt.

Greets and thanks for the help,

Thanks for the file, Kami, unfortunately it works fine here both on 1.6.8 and on my current code. If it is consistently repeatable for you, I would make sure to re-boot the machine, and if it still persists, I would run a memory-check. As for bad meshes being common, I agree, and I just use Moi3d to work on any object I have trouble with in Rhino - many times it seems to do a better job in this area.

Cheers,

JD

Hi JD
your right, this file is working fine too. I didn't reopen it after saving.
But when it was still open (after all other objects were deleted) it didn't work. Whatever ... it's not so much of a problem and it doesn't happen that often.
Thanks,
Kami
