Model-based manufacturing based on STEP AP242

Transition of product data model from 2 dimensions (2D) to 3 dimensions (3D) has significant impacts on the manufacturing processes. A 3D model as a representation of the product could be explored as the main source throughout the product lifecycle, and this enables smart manufacturing system. But to be used by all of the downstream customers, it must be delivered in a neutral CAD format, especially STEP AP242. Presentation and representation information in STEP AP 242 can be considered to build a system of model-based manufacturing by handling an automatics process planning. A process design structure is proposed to handle sufficient information in design file as an input to a model based manufacturing system.
