I want the Gerber exporter to export exactly what I draw.  And I will
draw exactly what the boardhouse wants.  And I don't want the PCB
program to complain if it assigns semantics in a different way as the
boardhouse.

If somebody insists on 3D models in a PCB layout tool, then there need
to be separate drawings for the boardhouse and the 3D model.  And the
programm please work well without any of the 3D stuff drawn.

No, but I guess they will tell me, and then I will draw that.
