在图上迅速绘制新格网

Drawing A new Gridding on Map

随着科学发展和创新意识的增强,设计单位所设计出的厂房楼体在图上必须醒目美观,这就打破了图纸南北定向的格局。其建筑样的主轴线不一定与原图的格网平行和垂直,为了体现该建筑群体在国家同一格网上的位置,必须在该图上绘制国家格网。要绘制新格网,用坐标转换公式换算出另一系统的坐标值,在图四边截取16个相关位置,与相交的4个点相连,绘出4条纵横格网。其展绘方式十分简练,缩减大量手工操作,提高效率二倍以上。

With the scientific development and innovation enhanceing, the designed plans must be eye-catching appearance, which broke the pattern of drawing with North-South orientation. The main axis of buildings needn＇t run parallel and vertical with the primary map, in order to reflect position of construction groups at the national grid in the same location on-line must draw the national grid. To draw a new grid, the other coordinate value should be derived form. the coordinates conversion formula, then intercept 16 corrdative points on the verge of map, connect the 4 crossing points and 4 vertical and horizontal grids, this dawning way is very concise and reduces a large number of manual work, improves efficiency more than twice times.
