Working Drawing Package

Develop a Working Drawing Package from your updated technical drawings. A Working Drawing Package is a packet of drawings that gives the specifications necessary to manufacture a design. A typical working drawing package includes:

Assembly Drawing is a drawing of an entire machine or system with all of its components located and identified; it is not used as a manufacturing print. This may include Subassembly Drawings: two or more parts that form a portion of an assembly.

  • The purpose of the assembly and subassembly drawings is to locate parts with ballooning and parts list / bill of material.
  • As a rule, dimensions are not given on assembly drawings. If dimensions are given, they are limited to some function of the object as a whole.

Detailed Drawings

  • Orthographic drawings with dimensions and an isometric view required for each fabricated component.
  • Specification drawing for all purchased components (include manufacturer’s part number used for prototype)

Cost List of Material

  • List all components in system
  • Identify part number, units, and quantity
  • Include cost of each purchased or fabricated part
  • Estimate cost for production quantities
