Can you even do that? Make a region (for extrusion) uisng non coplaner 3D points? To my knowledge you cant...but thats why im posting....somebody may know?
As far as I know you would have to do a projection of the points.

I also thought a region has to be coplanar - it doesn't have to be in the x-y plane but all in the same plane.  Any 3 points will be all in a single plane.
In vba i don't know if you can create a region from 'entmake' (or its equivalent in vba), but you could send an AutoCAD command to create it.
Same with a solid, though pretty sure only way is with an AutoCAD command.
