实际工程中的建筑表现图图幅较大,灭点出图板的情况是一个经常遇到的难题。远灭点尺是经我近年来不断思考研究的一项发明成果。视线尺是应用视线迹点法原理而构想的辅助求透视的工具,具有独创特色。估画透视的研究具有实用价植,其中提出的“透视高度=透视系数×真高”,并结合视线尺求透视系数的方法是解决此类问题的创新方法。两种透视尺经样尺试制,进行了数值分析,并结合实际工程进行了试画及改进。

Large architectural presentation drawings are generally used in building trade. The vanishing points outside the drawing board make things difficult. This paper is on the theory and practice of constructing perspective without vanishing points. Distant-vanishing-point device is my achievement resulted from dilligent study. Line-of-vision scale, which is conceived in the principle of intersecting points, is a creative drawing-aid for perspective. The method to estimate perspective is of practical value. In the paper I suggest that the height of a line in perspective equals the perspective-coefficient × real height of a line. With the aid of line-of-vision scale to find out perspective-coefficient is a creative method for such problems. The sample products of two devices and trial perspective drawing with its improvement have been made. And the numerical analysis has been done.
