Excerpt from Advanced Shop Drawing: Prepared in the Extension Division of the University of Wisconsin Assembly Drawings. - There are several types of assembly drawings. Among these are Outline or Setting Drawings, Diagram Drawings, Assembly Working Drawings, Part Assembly Drawings, Erection Drawings, and General Assembly Drawings. An outline assembly drawing shows the machine only in outline with no attempt at details. Center distances and over-all dimensions are given. Such an assembly is shown in Fig.1. An outline assembly drawing is used both for catalog illustrations and for showing prospective customers an outline of the machine. In such cases only the general appearance of the machine is necessary. A diagram drawing, Fig.2, gives either a sectional or an external view of the whole machine. In this kind of an assembly all the parts are either numbered or named. A list of parts is included on the drawing. Pattern numbers are sometimes given. An assembly working drawing is used when only a few machines are to be made. Each part is fully dimensioned. This makes it possible for the mechanic to build the machine from the assembly drawing instead of having to refer to several detail sheets. By this method a great deal of time is saved in the drafting room, since each detail does not have to be drawn separately. Part assembly drawings are those in which only a few parts of the machine are shown. In such cases these parts should be shown in their relation to the whole machine and also to each other. An assembly drawing is made of these parts, each part being fully dimensioned. Complete dimensioning does away with the necessity of drawing details. Erection drawings are those used in the erection of a machine. Each part is numbered or named so that it may be easily identified. These drawings give the exact location of each part and the proper order of procedure in the erection of the machine.
