1. Choose Expand segment > By berm width.
2. Click the segment in Graphics.
3. Enter the information as shown, and click Apply.



Note: You are adding a switchback to this ramp, with an angle of 180 degrees and an inner radius of 2.5 meters.

The segment is expanded, and the switchback is added to the ramp.



4. Choose Edit > Point > Delete, and delete the points as shown.



5. Choose Expand segment > By bench height.
6. Click the segment in Graphics.
