Archicad currently allows creation of multiple Design Options within Option Sets, but each option variant exists independently—requiring full duplication even when options share common parts.
It would be very beneficial to introduce support for hierarchical sub‑variants within Design Options. For example:
- Parent Option: “One or Two Apartments” – controls a partition wall.
- Child Options: Different internal layouts for each of the two apartments (e.g., kitchen or bathroom arrangements).
Currently, these must be handled as separate, disjointed options. With hierarchical sub‑variants, shared elements could stay in the parent option, and only the varying parts would be defined in child options. This would make managing complex, multi‑level alternatives much simpler and less error‑prone.
Why this is useful:
- Avoids duplicating entire designs for minor variations.
- Keeps shared geometry in one place, ensuring consistency.
- Reduces time and mistakes when working with complex, nested alternatives.
- Maintains project organization and clarity in scenarios with multiple phases or nested design choices.
