不论是建筑机械还是农业机械,都属于机械类,应当遵守机械制图的标准,应用机械制图法画建筑机械,不能用建筑立面图、平面图和剖面图来表示建筑机械。因此,我建议建筑工人也应学点机械制图,应用机械制图方法来绘制革新机具图。 Whether it is construction machinery or agricultural machinery, it belongs to the machinery category. It should abide by the standard of mechanical drawing. The construction machinery should be painted using the mechanical drawing method. The construction machinery cannot be represented by building elevations, plans and sections. Therefore, I suggest that construction workers should also learn mechanical drawings and use mechanical drawing methods to draw innovative machine drawings.
