Hi Jd, Hope all has been well since Anaheim, was a long time ago now...

I encountered this error today when enabling fire from within solidworks:

Yes, I hope you have been well too. It looks like SolidWorks is returning a null array (DBNull? how many kinds of null do we need -- I'll put in a trap for this) for either triangles or normals on this face. Is this native SolidWorks geometry, or imported? Are you able to check if you can force a valid mesh to be created by changing the Image Quality for the part?

The geometry is all native. Image quality was at the red limit, but was not applied to all referenced documents - that fixed it straight away! Thanks!

Well, thank you for reporting, as I was not aware that this type of null could be returned from the calls I'm making to obtain tris/normals.
