利用ObjectARX实现AutoCAD图形换带投影

Using ObjectARX Achievement Of Transform Zone and Projection of the AutoCAD Drawings

阐述了利用ObjectARX实现AutoCAD图形换带投影的原理,即仅修改AutoCAD各图形实体的控制点坐标或边界坐标,实现不利用中间软件使AutoCAD图形自行"飞行"至目标坐标系统,这样不但保留了原有图形的各项属性,而且为用图者提供了方便。

This article introduces the principle of using ObjectARX achievement of transform zone and rojection of the AutoCAD drawings, namely only modifies the control coordinates or the boundary coordinates of all kinds of the Auto-CAD entities, realizes does not use the middle software to cause the AutoCAD drawings voluntariIy flying to the goal coordinate system. So retain all attributes of drawings and provide more conveniently to use drawings.
