About Bill of Materials

A Bill of Materials (BOM) is a list of components used by an assembly, which is displayed in a table. The table can be embedded into a drawing as an OLE file, or saved as a Microsoft Excel spreadsheet.

To create an embedded Bill of Materials:

  1. Click Draft tab > Drawing panel > New.
  2. Create the views of the active assembly that you want to be labelled, using the Draft tab > View panel options.

    The following example shows an assembly with 4 views:

  3. Click Annotation tab > Table panel > Parts List.

    Data is generated from the active assembly and displayed in the Bill of Materials dialog:

    • Components based on round primitives (cone, cylinder, torus, or spring) are specified using Length x Diameter.
    • A best-fit bounding box is used to specify sizes for components that are not based on primitives. This gives accurate sizes for components that are positioned at compound angles (for example, sliders).
    • If the part number and catalog of components are the same, but the descriptions are different, the description will be omitted.
  4. Use the Bill of Materials dialog to create an embedded Bill of Materials.
