To meet the needs of CAD/CAPP concurrent designing in Computer Aided Concurrent Engineering. This paper investigates the key of integration system designing. The representation scheme for defining and operating form feature based on manufacture, the protrusion form feature exchanging and the UI of the system with a manufacture enviroment are presented. And also an OODM—UIMS developed by the author is introduced. The concurrent design of CAD/CAPP is the bottleneck in integrating process.
