When you delete selected strokes using the Backspace (Linux and Windows) or Delete (Mac OS X) key on your keyboard, or by selecting Edit > Delete, only the stroke node is deleted—the underlying stroke path curve is not. To delete strokes and their underlying stroke path curves, use the following procedures.

To delete selected strokes

1. Select the strokes you want to delete.
2. Open the Outliner or Hypergraph.
3. Shift-click to select the curves associated with each selected stroke.
4. Press the Backspace or Delete key, or select Edit > Delete.

To delete all strokes

1. Do one of the following:
   • In the scene view or the scene painting view, select Edit > Delete All by Type > Strokes.
   • Click the Delete All Strokes icon on the toolbar.
