Dear Graphisoft Product Team,
I would like to submit a feature request regarding the Zone Tool in ArchiCAD.
Currently, the Zone Tool defines spatial boundaries primarily through wall recognition. While this is functional, it reflects a structural logic rather than an architectural one. In the philosophy of architecture, space is fundamentally defined by the floor — the ground plane is where human life begins, and enclosure follows from it.
From this perspective, I would like to propose the following:
→ Allow the Zone Tool to recognize and generate zone boundaries directly from a Slab's outline.
In practical terms, this would mean:
- Selecting a slab and automatically generating a Zone that inherits its boundary geometry
- Or allowing the Zone to stay linked to the slab boundary, updating dynamically when the slab is edited
Currently, the relationship exists in reverse — slabs can reference zones (via Related Zone fields introduced in AC24) — but zones cannot originate from slabs.
This feature would bring the Zone Tool closer to the true architectural concept of space: a vessel for life, rising from the ground. It would also create a more intuitive BIM workflow where space definition and floor definition are unified from the start.
Thank you for considering this request. ArchiCAD has always been the BIM tool most aligned with architectural thinking, and I believe this enhancement would deepen that quality further.
Best regards
Open
