摘要
在双道起坡甩车场高、低道之间插入水平直线段简化计算,采用CAD直接作图,使用回转、偏移、移动、延伸命令加快制图速度,图纸轮廓给出后,直接在图中标注尺寸,避免了复杂计算,成图速度快,所注尺寸满足设计精度。
Horizontal straight is inserted into high and low channels of double channel sloping spot place for simplifying calculation. Using CAD,and rotation,deviation,movement and extension command to quicken drawing speed,we label size in the picture directly after outlining drawings,which avoids the complicated calculation,quickens mapping speed,and meets the design accuracy.
