AutoCAD modeling in the "Mechanical Drawing" Teaching

In mechanical drawing the process of teaching,AutoCAD and basic knowledge taught mechanical drawing organically inte-grated,can better train students in space and space imagination thinking ability,improve their ability to map drawing and numeracy,and the integrated use of knowledge Capacity.In this paper,mechanical drawing widespread teaching of the key and difficult problems to the new teaching plan,namely the introduction of AutoCAD for mapping teaching.Descriptive geometry use it to solve the mid-point,line and surface characteristics of the projection;combination view of Dutu;cutaway view of the formation and painting;three view of the dimension and the assembly plans Dutu and numeracy problems.
