Daniel and Jonathan:

I'd like to concatenate two 3-D extruded mesh files. The examples in the 
users guide indicate this can be done, but I can't seem to get the 
examples listed there to work and was curious if this feature has been 
dropped or the convention for doing this has changed?

I've created two grids that I'd like to add together in the Z direction. 
Some of the cells have a thickness of zero, and need to be removed from 
the mesh. I was hoping I could do this be extruding a mesh that removed 
the 'empty cells', and then attach it to the other mesh. Is this possible, 
or do I need to handle all this in one extruded file?
