Geometry grouping

Named, live-synced groups of Rhino objects that scope every study.

Guide · 1 min read

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.

Best forRepeated and comparative studiesQuick, throwaway checks

For anything you'll analyze more than once, prefer a group.

Managing groups#

In the groups manager in the Systems view of the 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.

Build a group once, then run and edit in a loop. The group stores object ids, so each run sees the current model.

Grouping works the same for every study: Sunlight, View and Radiation all run over groups.
