Drawing Package

• Drawing Package = a group of drawings that communicate the details of a system or sub-system.

• Package Content

• Drawings for each component linked to parent assembly

• One or more assembly drawings

• 2D or 3D

• Assembled or Exploded

• Label all components

• Include a Bill of Materials

• Link to component drawings

• How-to-assemble drawings

• Examples . . .

Bill of Materials

• Definition:

• A listing of all subassemblies, intermediate parts and raw materials that go into a parent assembly showing the quantity of each required to make an assembly.

• Common format: Table with Columns

• Typically included on the assembly drawing.

Lab 6

• Blocks• Used previously for the house layout

(doors, windows).

• Can include attributes to a block that will allow you to enter unique information each time the block is inserted.

• Attribute information can be extracted and summarize into a bill of materials or exportable database file.

Lab 6 Issues

• Model Space – where geometry is created, dimensioned, etc.

• Paper Space – a layout where the drawing is prepared for plotting.

• Viewport – how the model is viewed while in paper space.

• For lab, right mouse click the Model Space Tab to create a layout.
