【Abstract】 By utilizing data exchange function DXF of AutoCAD, 3-D objects are generated parametrically with 3-DFace through a certain algorithm. The objects obtained by this method are more abundant than those by AutoCAD and more flexible to use. They not only enrich the 3-D objects in the environment of AutoCAD but also can be used to generate 3-D objects by using other high-level programming languages to construct complicated space model. The application of this algorithm to constructing spatial tower crane and spatial net frame is introduced at the end of this paper.更多还原
