针对标准件直接从实体模型投影生成的工程图不符合制图标准的问题,在建立符合GB规定画法的参数化图块模板与标准件参数化模型的基础上,提出了建立图块模板与标准件三维模型一一映射的映射机制。通过对SolidWorks二次开发实现这一机制,以实例证明这种方法的可行性。 Aiming at the problem that the drawings generated by the projection of the standard parts directly from the solid model are not in conformity with the drawing standards, based on the establishment of the parameterized block templates and the standard parameterized models conforming to the provisions of GB, Mapping Mechanism of One-to-One Mapping of 3D Parts. Through the secondary development of SolidWorks to achieve this mechanism, an example to prove the feasibility of this method.
