UV mapping tasks are quite common for rendering projects; most times the mapped items are pixels from a flat image, and the eventual goal is another flat image after rendering. The mapping process, though, can also apply to vector/curve entities. A flat orientation of curves can be remapped back to a 3D surface. The process allows coordination of features more easily than with the standard Autodesk® AutoCAD® 2D/3D toolset. These UV mapped entities can add detail to “Pen Plotter” style prints, or serve as construction geometry for even more complex modeling tasks.
