In this exercise, you will practice manipulating the editing controls to create smooth horizontal curves.
- Go to the bookmark Road All.
- Open the Model Explorer and turn off visibility for the Points of Interest layer.
You do not need the pushpin markers anymore, so you can hide them.
- Close the Model Explorer.
- Go to the bookmark Road Curve.
- Select the road and move the asset card out of the way.
- Right-click the road and then select Edit Curve so that you can view the scale pop-up.
- Experiment with moving the slider to see how it changes the curve. Finish with the radius = 600
- Click away from the road to deselect it.
- Select the road again and then click the Point of Tangency control.
This control moves the start and end point of the curve and also affects the radius.
- Drag the POT control sideways to see how it changes the curve.
- Undo the last action to restore the curve.
- Adjust the Radius control to smooth out the smaller curve to the right of this curve.
- Right-click the curve and select Curve Properties.
- Note the information provided about this curve, including the design speed, which constrains the maximum radius.
- Close Curve Properties.
