The realization of direct-adaptive slicing approach based on AutoCAD

The slicing of the data is a kernel to Rapid Prototyping. A daptive Slicing is an effective method to solving the contradiction between the precision and the efficiency in RP. through comparing the area of the sliced layer,a corresponding layer height is computed. A direct-adaptive slicing algorithm based on the second development technology of AutoCAD is put forward.Meanwhile,a comparison is made between the adaptive slicing and the fixed thickness slicing. Implementation details and results are presented.
