--- Comment #3 from Regina Henschel <rb.henschel at t-online.de> ---
The 3D-Lathe object and the 3d-Rotation object are defined by a 2D-path, which
may be open. This geometry is always placed on the XY coordinate plan. The
3D-Lathe object gets it third dimension by extruding in positive z-direction,
3D-Rotation object by rotating around the y-axis.

To give the objects a different position or direction, you have to use it's
D3DTransformMatrix.

BTW, I find it easier to define a 3D Scene directly in the file text, then by
macros. See for example
https://wiki.documentfoundation.org/Documentation/HowTo/Draw/Make_a_3D_Star.

One problem with the API is, that it does not provide a method for updating the
rendering without distortion.
