Seven types of dimetric drawing and three types of trimetric drawing are introducedby the author with an aim to help hasten the shift of the principles derived from varioustypes of dimetric and trimetric projections from the theoretical approach to the field ofpractical use,and to alleviate the embarrassing situation that only the simple methodscan be resorted to in drawing the pictorial projections by isometric drawing and cabinetdrawing.This would surely shorten the time needed in making a drawing.Furthermore,a set of special instruments have been designed for this purpose,which is given thename Multi-Angle Axonometric Drawing Scales.This article proposes a set of methods of the approximate drawing of ellipses on thesurfaces of the co-ordinate planes in the above mentioned ten types of Axonometric Pro-jections,supported by data obtained by the author.This makes it easy and accurate todraw these ellipses.An explanation is given of the idea of designing these stated scales,their construc-tions and uses.What is worthy of mentioning is that the author did not stop at procu-ring the necessary data,but has executed these on the drawing scales by using the formof the edges in different angles and the form of dimension scales,thereby greatly faci-litating their application.Needless to say,it will surely help promote the quality of theaxonometric drawings in various publications,such as textbooks,teaching graphs,tech-nical books and periodicals and catalogs for products.

为了使各种形式的正二测和正三测从理论研究转向实际应用,克服长期来人们在绘制轴测图时,多数只能采用正等测和斜二测等单调情况,以及提高绘图速度,本文推荐采用七种正二测和三种正三测,并设计一套绘制这十种正轴测的专用工具--轴测多角比例尺。本文提出一套近似作这十种正轴测坐标面上椭圆的方法和数据,使其既简便又准确.本文并阐明了轴测多角比例尺的设计意图、结构及使用方法,其特点是将理论研究所得的各种数据,采用不同角度的尺边及比例尺的形式制作在这套尺上,因而使用方便。它可以提高各种教材、产品说明书、技术书刊及教学挂图中的轴测图的绘制质量。
