Engineering Bill of Materials (BOM) is a list of unique mechanical components used in a drawing. The list is represented as a BricsCAD table entity (see Tables), and can be placed at any location in the drawing area. Each entity has its serial number (starting with 1), name, and the number of occurrences.
There are two options for BOM: listing top-level components only or bottom-level (parts) only.
By default the BOM table contains only three columns: number of a component, its name, and the number of inserts of this component in the assembly. The Configure option of the BmBom command allows to add more columns: Description, density, Volume, Mass, and parameters (for inserts of parametric components).
Multiple inserts of the same parametric component are grouped in separate BOM rows depending on the values of their parameters.
