The fixture parts that are in the database of platform are on the basis of 3D feature modeling of CATIA which has adopted the mode of parameter driving. Users can call the assembly model of typical fixture directly through the visual human-computer interaction interface; they also can modify and assemble the fixture parts, and then ana- lyze and calculate both location and clamp device of fixture, to accomplish the special fixture design rapidly.
