Development of CAD Tool for Layout with 2D-3D Interactive Functionality

Article of Honda R&D Technical Review Vol.22 No.1


In the process of designing industrial products, it is important to be able to review designs while referring simultaneously to 2D and 3D forms, and to be able to mutually reflect the results of these reviews in both 2D and 3D, in particular during layout work when the shapes of parts are formulated before specifications have been established. Functionality helping to enable these procedures to be conducted efficiently is demanded of the design tool, computer-aided design (CAD). Based on design procedures and the concrete methods employed in them, the operations that can be considered as necessary in CAD were outlined with a focus on the relationship between operations in 2D and 3D. A concept and functional requirements were formulated for new functions enabling these operations to be conducted, and these functions were realized as standard CATIA V5 functions. The use of these new functions, combining layout functions and 2D-3D association functions, has increased the efficiency of the design process from the concept stage to the layout stage.
