3D Chin-ping for 2 D

Chin-ping of an independent system can quickly be 3 D Chin-ping to 2 D, and easy operation, flattening out the 2 D surface can be directly used to create sub-version. 2D and 3 D interfaces are interrelated, they use the same tools, as long as an interface in any shape or modify the establishment of line, then another interface will also follow the established or modified. Shoemaster Chin-ping system is the shoe-making by experienced instructors, modelled on the manual methods of flattening out the research and development.
