BOM Filtering by Configuration for Assembly Steps

william_laceywilliam_lacey Member Posts: 13 PRO

I have an assembly with 20 configurations, each representing a step in the physical assembly process. In each configuration, new parts are unsuppressed while previous ones remain visible.

I’d like to create a drawing where each step’s BOM shows only the new parts added in that configuration. Right now, the BOM lists all previously assembled parts as well, which creates redundancy.

In SolidWorks, I could exclude parts from the BOM on a per-configuration basis. Is there an equivalent option in Onshape?

I’ve tried two approaches:

  1. Single assembly with all parts included and suppression controlled by configurations (current issue: BOM shows everything).
  2. Separate assemblies for each step, where I insert the previous step’s assembly and add new parts. This works for BOM filtering because I can exclude the inserted assembly, but it’s less convenient to maintain.

Is there a way to achieve per-configuration BOM filtering in Onshape without creating multiple assembly files?
