在绘制形体的三视图时,如果已知两个视图,要绘制的第三视图是左视图或者是俯视图,常用的作图方法是使用一条45°辅助线。这种作图法被习惯性地应用到Auto CAD软件绘图教学中。在Auto CAD软件绘图环境中这种传统的方法绘图效率低。文中通过实例提出一种应用于Auto CAD绘图环境下绘制三视图的作图方法,这种新的作图方法的原理是基于将传统45°辅助线作图法中俯视图、左视图相应尺寸的“宽相等”,转化为相应尺寸的“长对正”或“高平齐”的过程。新方法比传统45°辅助线作图法更加简单、直接,且效率高。
在繪製形體的三視圖時,如果已知兩箇視圖,要繪製的第三視圖是左視圖或者是俯視圖,常用的作圖方法是使用一條45°輔助線。這種作圖法被習慣性地應用到Auto CAD軟件繪圖教學中。在Auto CAD軟件繪圖環境中這種傳統的方法繪圖效率低。文中通過實例提齣一種應用于Auto CAD繪圖環境下繪製三視圖的作圖方法,這種新的作圖方法的原理是基于將傳統45°輔助線作圖法中俯視圖、左視圖相應呎吋的“寬相等”,轉化為相應呎吋的“長對正”或“高平齊”的過程。新方法比傳統45°輔助線作圖法更加簡單、直接,且效率高。

When drawing three views of an object, if two views are given, this third view from the left or above may be always developed by the use of a mitre line at 45° . This traditional plotting method is habitually applied to drawing teaching of Auto CAD software. The drawing efficiency of this method is low in the environment of Auto CAD software. In this paper, a new plotting method of three views is applied to the environment of Auto CAD software was offered by examples. The principle of this new plotting method is based on the conversion that the equivalent width dimensions of the views from above and left can be converted to corresponding and equivalent length dimensions or height dimensions. Compared with the method of ‘a mitre line at 45°, this new method is simple and direct and has higher drawing efficiency.
