I am looking for a tool or process that will let me wrap a 2D drawing onto a 3D cylinder and use the resulting curves and points as extrude paths and construction geometry for "engraving" the solid. I use the Silhouette Cameo and Shapeways 3D printing service to build up scale model rockets. It would be helpful to do all of my layout work in a 2D sketch with the curves representing panel lines, hatches, doors, rivet heads and the like. The latter stages of my imagined workflow would entail wrapping the drawing around a cylinder having the correct length and diameter and then using the curves to add detail. Any suggestions would be much appreciated.
