Abstract: CAD, a powerful tool for product innovation, has been widely accepted as an individual facility more than a tool for virtual collaborative product design. For the better regulation of the CAD/CAM application, a principle of standardization of CAD application is proposed, from the view of information integration. It involves the master model, file naming, attributes input and attributes reuse，depth backup, reference set，layer，title block, part list auto-generating. Using the tool of UG/Open, a software system has been implemented for CAD application standardization and its verification. It is proven that the standardization of CAD application and its software can bring a better regulated CAD application, in which, the data collaboration，CAD model share and its data exchange, a safer master model can be achieved, and then a higher level of CAD application can be expected.
