Working with groups

The Salome platform offers such a useful functionality as creation and editing groups of subshapes of a geometrical object which makes handling subshapes much easier. However the functionality is available in the OCC viewer only. If other viewer is used in your project by default, you can toggle the OCC viewer via Preferences / Viewer background / OCC viewer.  

To perform operations with groups:

In the main menu select New entity > Group.
