Std 15: Detailed, Assembly, and Systems Drawings
Detailed drawings have detailed orthographic views with dimensions so that parts in the drawings can be reproduced exactly the same as what is given in the drawing. This can include linear and angular dimensions, center lines, hidden lines, surface finished, as well as, other specifications about the part.
Assembly drawings are typically exploded views of an assembly. They most often include a bill of materials (a listing of the sub-parts used to construct the assembly).
