The Research Work is carried out on the approach to develop GUI based software which useful for a CADD (Computer Aided Design and Drafting) and Concurrent engineering approach. Because with the use of this developed system all phase of product development Design, modeling and analysis is work on a bench. The work reviews the procedural steps involved in the design of couplings and the development of the software package using visual basic as a tool for the design. This system is carried out on the case study of flange coupling and standard design equation being carried out together with the use of programming software and use creo as modeling software after getting output from the designing software.
