Engineering Drawings Dimensioning The Legal Context

• Dimension with intent to manufacture • Engineering Drawing: • All dimensions from one setup coming • Binding document or set of documents that from the same datum disclosed graphically and in text the form • Parts with many dimensions may need and function of an object. two or more different drawings or • Legally binding if created by or approved enldilarged views. (i. e. stamped) by a professional engineer.

Bill of Materials

• Bill of Materials Contents: •Part No. • Quantity • Material/Stock Size • Sheet # •Source • Bill of Materials are needed for each full and sub Bill of Materials assembly • If the same part appears in multiple subassemblies it only needs to appear once in the drawing package. • Common format: with Columns • Typically included on the assembly drawing.

• Do not need to be fully dimensioned in drawing unless modified after they are Stepper Motor purchased

• Add a note for the material giving the part number and contact info of the company the part was purchased from
