摘　　要：提出一种基于网格划分的工程图视图分离方法,首先对工程图图元区域均匀划分网格,然后根据图元几何信息设置网格属性,再根据网格的连通、包含关系判断图元的连通和包含关系,最后将所有具有连通、包含关系的图元归为同一视图实现视图分离。本方法过程简单,具有较好的容错性,并适用于多视图包围盒重叠的情况。A view separation method for engineering drawing based on meshing has been put forward in the text. Firstly, the graphic＇ element has been separated uniformly into mesh. Then the mesh attribute has been set up as per drawing elements＇ geometric information. According to the meshes＇ connectivity or inclusion relations, the graphic elements＇ connectivity and inclusion relations have been judged. Finally, all graphic elements which have connectivity or inclusion relations have been considered as one view to realize the view separation. The method is simple in process with good fault tolerance, which is suitable for multi-view overlapped bounding box.
