Geometry Grouping
Named, live-synced groups of Rhino objects that scope every study.
A group is a named set of Rhino objects that a study runs over. Groups reference Rhino object ids rather than frozen copies, so they stay in sync as your model changes — edit, move, or replace objects and the next run reflects the current model.
Why Groups
Define a group once — "tower facades", "podium roofs", "site context" — and point any study at it, instead of re-picking the same surfaces every run.
Groups also make studies comparable: run the same study across several groups and read one option against another, for example two massing variants grouped separately.
| Geometry group | Ad-hoc selection | |
|---|---|---|
| Reusable | Yes — named and saved | No — one run only |
| Live sync | Tracks Rhino object ids | The current selection |
| Best for | Repeated and comparative studies | Quick, throwaway checks |
For anything you'll analyze more than once, prefer a group.
Managing Groups
In the groups manager in the Systems panel: create a named group, select objects in the viewport and add them, remove objects you no longer want, rename or delete as the model evolves.

Grouping is study-agnostic: Sunlight Hours runs over groups today, and View and Radiation are wired to the same scope as their Rhino adapters land.
