Working drawings are the primary means of communication between designers and fabricators.
They describe each part needed to make a product. There are three kinds of drawings in a
complete set of working drawings:
1) detail drawings,
2) assembly drawings, and
3) the bill of materials.Sometimes, the assembly drawing and the bill of materials are combined into one drawing.
Assembly drawings describe how the parts are assembled. They are rarely used by the person
making a part. Instead, they are the instructions for the person or persons responsible for the
assembly of the product. Every assembly drawing needs a bill of materials or BOM. The BOM is
a list of all the parts needed to assemble the product or sub-assembly. In practice, the person
assembling the product will first verify that all the parts are available before assembly begins.
Drawings are also used by the maintenance organization when a repair or upgrade is
necessary. For this reason, maintenance information should be included as notes in the detail or
assembly drawings. Finally, the design and the maintenance organizations need information
about the changes made to the product over the years. In this role, drawings are historical
documents that can be used to reconstruct the original design and all the changes. This
information is usually found in the change block.
