视图中呈类似性同一平面的可构性研究

Structuralization of Similar Planes on the Views

针对视图中呈类似性同一平面的可构性,分别研究了视图中呈类似性投影面垂直平面及一般位置平面,可构分两种情况,一是视图中呈类似性同一平面轮廓线是否可构,二是当视图中呈类似性同一平面其轮廓线不可构时,轮廓包围区域是否构形。视图中呈类似性同一平面,不论是几边形平面,在已知二视图时,组成面的轮廓中呈类似性投影面平行线均可构,当轮廓线可构时,构形的方法也多样化。二视图中呈类似性的投影面垂直平面可构,三视图中一般位置平面仍可构。

The similar vertical plane of projection plane and the similar incline plane on the views are studied respectively.Two situations are discussed.One is when the contour line of the similar same plane can be constructed,and the other is when it can not be constructed.In either situation,the planes are both constructable.
