BOM Status in BricsCAD Mechanical Explained

Quick answer: Every component has a BOM status property controlling its behaviour in Bill of Materials tables. This confirms the Terminal status example referenced on this hub’s BOM types page.

The Four BOM Status Values

Regular: appears in a Bill of Materials at the same position as the assembly structure, using the default value for the selected BOM mode.
Transparent: acts as a transparent container for its subcomponents, the component itself doesn’t appear, but its subcomponents can, depending on their own BOM status, position in the assembly structure, and the BOM table’s mode.
Terminal: treated as a leaf component with no subcomponents, useful for complex parts or standard components.
Excluded: the component and every one of its subcomponents stay out of the Bill of Materials entirely.

Setting BOM Status for an External or Root Component

Open the file containing the component.
Select the root component in the Mechanical Browser.
Set its BOM status property.

Setting BOM Status for a Local Component

Select the component in the Mechanical Browser panel.
Right-click it to open the context menu.
Choose a status from the BOM status submenu.

You can’t set BOM status via the context menu for a local component that’s inserted into an external component, open the component containing it directly instead.

Frequently Asked Questions

Which BOM status would I use for a standard part like a bolt that shouldn’t show its internal structure? Terminal, treating it as a leaf component with no subcomponents.

Can I hide a subassembly itself while still letting its individual parts show in the BOM? Yes, set it to Transparent, it acts as a see-through container, letting subcomponents appear based on their own status and position.

Why can’t I set BOM status via the context menu for a local component in this drawing? If it’s actually inserted into an external component, you need to open that external component directly to change its status.

What happens to a component’s subcomponents if I set it to Excluded? They’re excluded from the Bill of Materials too, not just the component itself.
