Plain-English definition
Instead of tracing the same wall five times, an assembly lets one wall run produce framing LF, drywall SF, insulation SF, base trim LF, and paint SF according to the configured rules.
When assemblies help
- Repeated walls, rooms, floors, ceilings, or exterior systems.
- Scopes where length, area, count, and material quantities are tightly related.
- Early estimating where consistency matters more than hand-entering every derivative quantity.
When not to use an assembly
Do not force assemblies onto one-off conditions. If the system changes room by room or detail by detail, separate measurements may be clearer and safer.
Review generated quantities
Assembly output is only as good as the rule behind it. Before export, check the source measurement, category, room assignment, and generated quantities for reasonableness.
