The complex columned entity design is very difficult. The paper mainly discussed 3D modeling technology, bought forward the NURBS (Non-Uniform Rational B-Splines) unrolling and rolling algorithms, explained the NURBS circle and cylinder NURBS surface unrolling&rolling and analyzed the unrolling and rolling error. The unrolling&rolling programs which run in the CAD software have been developed. By a sample, It shows that the unrolling&rolling program will make designing the complex columned entity more easily and efficient. The program of the unrolling&rolling algorithms is applied successfully in the camera part model.
