Working Drawings
Working drawings are meant for first-level prototype realization. The notes in working drawings need not be very specific. The purpose is to realize a prototype for evaluation as quickly as possible. It is acceptable to leave certain issues to the shop floor personnel’s discretion. This way new inputs may also arise for later refinement and final documentation. Similarly, it is not necessary to define close tolerances in working drawings. Loose tolerances are good enough at this stage.
Often as-built drawings are made after the completion of prototypes for review and corrections before final documentation is initiated.
