摘　　要：通常三维图形的绘制远比二维图形复杂,而且不容易表达清楚.计算机绘图技术的普及并逐步提高之后,就可以利用AUTOCAD的设计分析功能,直接生成三维实体模型,便于技术交流与设计方案的修改完善.然后,再将绘制的三维实体模型自动转变生成二维图形———视图和剖视图,使工程形体的表达更加清晰易懂,其绘图方法也简单易行.可在提高绘图效率和绘图质量的同时,也使得图形的正确性大大提高.Engineering technique drawing is a way to make a construction into the projection drawing by projective principle,which is the basic element in building structure and equipment manufacturing.A two-dimensional graphics is usually drawn in building structure,while the 3D drawing,being difficult to express the building structure clearly,and is always saved because of its complication.With the popularity of computer drawing techniques,the 3D models will be created by Auto CAD technology,therefore,the technological exchange and design modification can be made easier.The 3D drawing will be automatically changed into a plane figure——view and section view,and the expression of building structure will be cleaner and easier to understand,which not only omits the complicated process of 2D drawing,but also avoids the technical infraction of unwanted lines in the view.The drawing technique would improve the drawing efficiency and design quality,at the same time,the drawing correctness would be greatly raised.
