> [!TIP]
> ### Requirements
> 
> Select the mesh(es) or polyline(s) or set(s) of polylines and launch the command.

1. Select a **View Direction**.
2. Select the **Type of result** you need:
  1. **2D Contour (planar)**
  2. **3D Contour without auto-intersection**
  3. **3D Contour**
3. Enter the **Draft angle** or 0 if no draft angle is required.

> [!WARNING]
> ### Notes
