The pre-development of CAD means the designers familiar with production and the technicians skilled in computer application develop CAD application software aiming at enterprise's special function requirement. In light of the design system of Nanjing Kangni New Technology of Mechantronic Co., Ltd and the factual requirement of PDM during the corporation implement information-engineering, this paper pre-develops SolidWorks partly , adds some new function modules to it on the base of thorough analysis of the key technology of SolidWorks pre-development.Firstly, the new function modules including SolidWorks KN_ToolBox, the automatic query and label of size and tolerance, the insert of national and super sign are added, to make it true that SolidWorks's function is extended.Secondly, this paper adds the function modules of coding the production drawing, customizing the DBOM of products based on SolidWorks.Finally, the added function modules are integrated with SolidWorks seamlessly, and resolve the problems which desiderate in the product design system of Nanjing Kangni New Technology of Mechantronic Co., Ltd. |
