It is necessary to reduce the manufacturing lead time tor every product to compete in the global market. There is a potential for time saving in the Computer Aided Drafting process. In the modeling process, the design can be automated by using parametric modeling technique. This paper presents about parameterization of a direct type drive wheel assembly of an Apron Conveyor using Pro/PROGRAM, a feature in Pro/ENGINEER Wildfire 3.0 software by controlling the geometrical parameters. This work is intended to reduce the overall modeling time of an assembly. This process is significantly simplified by reducing the number of modeling steps. This reduces the modeling errors and improves the product quality. The end user need not have design skills or knowledge of using complicated CAD systems.
