Notes:

• The association between contour lines and the DTM is lost during conversion. These are then treated as discrete elements and cannot be re-associated with the model.
• Elevation points are converted to normal 3D points; labels stay as text.
• Special lines are re-created as discrete 3D lines in the corresponding color. They can be combined to make polylines.
