基于Inventor的工程图样中线条的人工编号方法

Manual Serial Number Method for Lines in Engineering Drawing Based on Inventor

在Inventor二次开发生成工程图样的过程中,需要给工程图样添加各种标注,标注的添加以视图中的线条为基础.对于系列化的零部件,其三维模型变动前后视图中同一线条的序号必须保持不变才能准确添加标注,但系统序号随着三维模型的改变而变动,所以需要为视图中的线条添加人工序号来满足要求.通过对视图中线条的分析,根据其形状特点形成线条集合,并进一步找到了根据线条的相对位置关系编排人工序号的4种方法.对应线条的人工序号固定,保证了工程图样中各种标注位置的准确性.

A variety of signs should be added to engineering drawing during the drawing generated by developed Inventor. The signs are added to engineering drawing based on the lines in the views. For serialized parts, the serial number of same line in the view must be changeless before and after variation of the 3D model. The system serial number changes with the change of 3D models, so manual serial number should be added to the lines in the view. Through analysis of the lines in the view, some kinds of line sets form according to its shape characteristics. Then four methods of arranging manual serial number are found by the position relationship of the lines. Accuracy of marked position in engineering drawing is ensured by the manual serial number changeless of lines in the views.
