Depends how the model was generated. The flags just switch thecoord axis
around to fix problems with polys facing the wrong way
or the object being rotated. For instance, a 3DS Max DXF export
requires -Y-Z on the command line as Max treats Z as being up and
Y as being into the screen. So -Y-Z swaps the Y & Z axis to get the
object the right way round.
