These summarize and communicate your design and must be sufficient to fabricate the design.

Drawings should be roughly to scale and must include:

1. a rendering of your design
2. an isometric assembly with components 'called-out' and correlated by either number or part name with the Parts List. (NOTE: A Parts List is necessary if parts are numbered in order to associate names with numbers. It is preferrable to refer to 'names' rather than 'numbers' subsequently in the report.)
3. details clarifying component connections and joints and
4. other details as necessary. Use professional conventions. Include all dimensions.

Do not draw details of standard `off-the-shelf' hardware like nuts, bolts, washers, castors, etc., just specify them in the Bill of Materials and call them out in the drawings.

The bill of materials lists:

structural products and their specifications (materials, sizes and quantity) necessary to fabricate Parts and
off-the-shelf hardware. It may include weights and costs. The Parts List and Bill of Materials may be combined.
