Abstract
AbstractThe purpose of this research is to make design change automation possible by parametric sketching and design associability in 3D CAD. Applications of the technology in liquid food packaging machinery and its advantages are presented in this paper. For regular shapes such as circles or lines, parameters are used to link dimensions of relative parts while for irregular shapes such as curves and surfaces, associability is used to do the work in an assembly. Same merit applies to designs of other machineries, on reducing design time and design mistake, enhancing consistency and ease of documentation, therefore liberating designers from redundant day-to-day routine computer-paperwork to make more innovative contributions to their jobs. Several 3D design tools and database software were applied in the research.
