Assembly drawing. General information

An assembly drawing (code – SK) is performed at the stage of development of working design documentation based on a technical or draft design. It contains (GOST 2.109-73):

a) an image of an assembly unit (with a minimum but sufficient number of views, sections and cross-sections), which gives an idea of ​​the placement and interaction of the components that are connected according to this drawing, and ensures the possibility of its assembly (manufacturing) and control. The image of simple products must be limited to one view or section, if this is sufficient for assembly (Figure 6.1.1).
