Abstract Flattening of 3D surface is one of the most difficult problems in thedevelopment of CAD system for stuffed toys. So far there is still no commercialapplication with the function of flattening 3D surface for such toys. By adopting spring-mass model, 3D surface flattening is implemented through optimizationalgorithm. The geometry constraints during optimization are solved by graphic method, and this method achieves the expecting results.
