DXF2papercraft converts a polygonal 3D model stored as a DXF file into a plain drawing in the form of a 2D DXF file. This requires the program to "unfold" the 3D model. The result is a flattened pattern of connected polygons. All edges of a polygon which are unconnected get a so-called glue tab in addition. This pattern is called a papercraft model, and it can be used to build a shape that resembles the original 3D model from paper or cardboard. After all pairs of tabs have been glued together, the paper model corresponds to the 3D object. The final model can be reinforced by fiber glass and resin to obtain a rigid, resilient structure.
