| 摘 要： | 本文提出一种算法，先把含有全剖视图的视图转化成相应子实体的视图，由此构造出三维子实体，再把三维子实体合并，提供了一种利用全剖图帮助重建三维实体的途径。并在AutoCAD平台上验证了算法的有效性。本算法主要适用于剖切平面在实体对称位置的全剖视图，对于利用其它类型的全剖图帮助三维重建的算法也做了初步探讨。

| Abstract: | An algorithm, which can automatically construct 3D objects by m eans of some categories of 2D orthographic cutaway views, is proposed. First, the in putted drawing is transformed into views of some sub domains of the 3D object, i n such a way that all sub domains can be reconstructed. Summing up all the sub d omains gives the final 3D object. A reconstruction code according to the algorit hm was written in AUTOLISP and runs well on the AutoCAD platform. |
