Warum es wichtig ist
This article turns three real JaMo App commands into a coherent engineering workflow rather than isolated feature bullets.
Abschnitt 1
Entity logic comes first
If the IFC entity assignment is wrong, every downstream property and quantity discussion starts on weak ground. That is why IFCmap matters first. It establishes what the receiving system is supposed to understand the element to be.
Abschnitt 2
Property sets should not repair bad classification
Property sets are often treated as a rescue layer. They are not. Pset_map is most useful when the entity assignment already makes sense and the question is whether the expected standard properties are present and attached consistently.
Abschnitt 3
Quantities need the same discipline
Qto_map is the same logic applied to quantity information. If the exchange depends on quantities, they should be prepared and checked as part of the workflow, not assumed to emerge correctly at export time.
Abschnitt 4
Why the sequence matters
The benefit is not elegance. It is risk reduction. A team that sequences entity, property, and quantity preparation has fewer surprises at handover and a cleaner basis for model QA.
Praktische Erkenntnisse
- IFC entity assignment should be stabilized before property and quantity work.
- Property sets are not a substitute for correct entity logic.
- Handover quality improves when IFC prep is treated as a sequence instead of one late export task.
Realitätscheck
- If office standards for IFC output are still vague, no mapping command can fully remove ambiguity from handover.
