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.

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。
