EMBEDDING GENERAL CONSTRAINT RESOLUTION INTO A CAD SYSTEM
Computer aided design (CAD) has facilitated designer’s task by automating many of the activities involved in a conventional design process. This can be further augmented by use of constraints in CAD systems. However there is still need for incorporating general constraints. This paper highlights some of these constraints. Constraint modeller software that incorporates these constraints is described here. Based upon this constraint modelling approach, a new constraint modeller-CAD interfaced system has been created. This system can offer combined advantages of these two systems and has been demonstrated in modelling, assembling and simulating the action of part of a confectionary wrapping machine.
