Abstract SolidWorks software Is a popular software of 3D solid model in the current field of CAD。This software has three characteristics,such as powerful function,easy to use and technological innovation。In order to simplify the process of modeling, SolidWorks also provides good openness and compatibility, through hundreds of API interface, can easily use other programming software of SolidWorks for secondary development, eliminating the need for large repeat drawing modeling work。 Thus, the task of the design personnel is reduced, the work efficiency is improved, and the design result is accurate and reliable, and is not easy to make mistakes。
This design by using VB。 Net application development platform, takes the idea of parameterized design as the leading, related calls SolidWorks API interface and the Software SolidWorks for secondary development, so as to realize the simplified model of diesel engine related parts of the。 The article based on dimension driven parametric modeling method and the parametric feature modeling based on, for example, respectively of diesel machine body and crankshaft modify the dimension of, parameter modeling design。 Application of parametric modeling method based on dimension driven, through the program call related functions to access the built frame of diesel engine model size and modification; application of parametric method based on feature driven, also known as full programming method, reflect each modeling step of diesel engine crankshaft。 Through the relevant parameters control the model generation。
Keywords: model simplification; SolidWorks for secondary development; VB。NET; parametric modeling; API
