archiSum automatically groups zones by apartment number (or any custom property), calculates total areas for each group, and writes the results back to zone properties: all without leaving Archicad.
Typical use case
You have a residential project with 40 apartments split across 5 stories. Each apartment is several zones (living, kitchen, bedrooms, bathroom, balcony). You need the total net area per apartment written into a property on every zone of that apartment, so schedules and listings show the right number.
Why archiSum instead of a schedule
- Writes totals into zone properties: your existing schedules and tags just work
- Respects measured vs calculated area choice per zone
- Filters by layer and zone category, so stray or draft zones don't pollute the totals
- Full undo support: nothing is permanent until you confirm
