This page describes the Rig Mode: a dedicated working mode in Cascadeur used for creating  and altering character rigs.
All works with rigs is performed in the Rig Mode.

To enable this mode:

Click the Rig mode button on the Toolbar:

Once the Rig Mode is activayed, you will see the Rigging Tools panel at the left side of the screen:

And if the character already has a rig, this rig will be visible in the Viewport.

To disable the mode, click this button again (or click Generate rig on the Rigging tools panel).
Keep in mind, though, that if the character already has a rig, closing Rig Mode will re-generate this rig.
