Bill of materials

An Inventor BOM your buyer can order from

A parts list tells the workshop what to make. Purchasing needs to know what to buy. SheetPilot gives both, from the same model.

Page one: what to order

The first page of the BOM is a consolidated order summary: how many sheets, how many bars and tubes, bearings, keys, chain and fastener sets the project needs — in buying units, not modelling units.

  • Bars, tubes and pipes counted in 6 m lengths, with cut allowance added per cut. Example: 10 pieces of 600 mm become 2 bars.
  • Fasteners grouped as sets, e.g. “M8x20 + nut + washer + spring washer”.
  • Project quantity — build the same machine 3 times? Enter it once and every quantity follows.

The detailed BOM

After the summary comes the full bill of materials: item, description, material, quantity and make for every part and bought-out item, matching the balloons on the drawings.

Review and edit before you export

The BOM opens in an editable window first. Add the make, supplier notes or extra information, then export to Excel for purchasing or XML for your ERP.

Questions

Can I export the Inventor BOM to Excel?

Yes. SheetPilot exports the order summary and the detailed BOM to Excel, and to XML for import into other systems.

Are fasteners in the BOM even if they are not modelled?

Yes. Fasteners can be listed in the BOM as sets without modelling them in the assembly.

How are bar lengths calculated?

Pieces are grouped by section and counted in 6 m stock lengths, with a cut allowance added for every cut.
