第八章 Assembly Drawings：An assembly drawing is a drawing representing the relative working principle of the machine. When design, engineers first construct the assembly drawing, then design the detail drawing based on the assembly. The above-discussed methods for representing parts, such as view, sectional views,cuts and partial enlargements, can also be applied to assembly drawings to represent machines and assembly units. Machines and assembly units consist of multiple parts, therefore, in comparison to the detail drawing, an assembly drawing has special and other special and other specified representations.8.1Introduction of Assembly Drawings:We talk about contents of assembly drawing, include the a group of views, necessary dimensions, technical requirements and title block, No.,item block.
