True. Our discussion centers on the occasion when a 3D modeler *wants* to add a 3D model to an FDM. > Have a look at the attachment this is the 747 flying sideways,quite happily, > as a 737.If the 3D model affected the FDM then this should not fly.

Trust us (myself, Jim, Tony ...), we've looked at this situation 'til we were blue in the face.
