摘　　要：提出了一种基于点与直线关系从正轴测画隐线图建立平面立体线框模型的新方法。给出了基于点线关系的基本约束,根据正轴测画隐线图中隐含的点与直线位置关系建立约束方程和一个线性系统,通过求解该线性系统,得到平面立体的三维信息。该方法适用于解释平面立体的正轴测画隐线图。用算例进行了验证。Aim. In the full paper, we start with a review of relevant papers^[1-7], including five papers authored by NWPU staff members^[3-7]. Then we propose a new method of reconstructing threedimensional models from two-dimensional hidden-part-drawn line drawings. In the full paper, we explain our new method in detail; in this abstract, we just add some pertinent remarks to listing the two topics of explanation： （1） basic constraining relationships and （2） the interpretation of two-dimensional hiddenpart-drawn line drawings; in topic 1, we derive two new theorems on basic constraining relationships that are, we believe, more effective; in topic 2, we utilize the above-mentioned two new theorems to do the interpretation. Our new method is, we believe, valid for the orthographically axonometric projection of planar object. Finally we give two illustrative examples that show preliminarily that our new method is feasible and effective.
