[0003] CATIA is a CAD / CAE / CAM integrated software under Dassault, France. After more than 30 years of development and continuous innovation, its leading position in the fields of CAD / CAE / CAM and PDM has been recognized worldwide. CAITA is widely used in aerospace, automobile manufacturing, shipbuilding, machinery manufacturing, electronics, electrical appliances, and consumer goods industries. Its integrated solutions cover all product design and manufacturing fields. Its unique DMU electronic prototype module function and hybrid modeling technology have promoted the improvement of corporate competitiveness and productivity. DELMIA software is a product developed by Dassault, France, including three major modules: DPE (Digital Process Engineer) for manufacturing process design, QUEST (Queuing Event Simulation Tool) for logistics analysis, and DPM (Digital Process Manufacturing) for assembly process analysis.
