1. Click points inside the graphic scene. If you need more information: refer to [Define points](/v1/docs/cyclone-3dr-enteringpointprocedure). These points will be the "passing" points for the curve (passing exactly by all points).
2. If you want to delete the last point, press **Del** or **BackSpace** key.
3. If you want to exit the command without validating the current CAD curve, use the **ESC** key.
4. When you have finished the CAD curve, press **Enter** key. You can then start a new CAD curve.
5. If you have finished drawing CAD curves, press again **Enter** or **ESC** key to close the dialog box.

> [!TIP]
> ### Tip & Trick
> 
> Press **C** to close / unclose the curve.

> [!WARNING]
> ### Notes
> 
> Positions of control points are reset after each new click or point deletion.
