What it does
Auto BOM opens the MECHCAD BOM Lab window. It builds a parts list from the open assembly, with pictures, sizes and quantities. You can add brand, material and colour, then export Excel or PDF with an exploded view and balloons.
Where to find it

Steps
- Open an assembly, then click Auto BOM.
- Check the list. You can type Brand and Material directly in the table. Double-click Color to pick a colour.
- Click Edit Balloons to arrange the exploded view and balloon positions, then Preview Views.
