Recalculating the spline

In the network editor you can recalculate the course of a road or a connector on the basis of the points, for example if you have inserted new points and then wish to adjust the course of the road. You can select whether the position and the height of the points are to be recalculated. Vissim calculates the distance or connector for a harmonious course with a spline.

1.  On the network object sidebar, click Links.

2.  In the network editor, right click on the desired link or connector.

3.  To select further links or connectors, hold down the Ctrl key and click the other links or connectors of your choice.

4.  On the shortcut menu, click the desired entry:

Element	Description
Recalculate Spline	Recalculates the x, y, z coordinates for the spline
Recalculate Spline (X/Y Only)	Recalculates the x, y coordinates for the spline
Recalculate Spline (Height Only)	Recalculates the z coordinates for the spline. If the position and z-offset of the first or last two points of the link cause slope conditions that result in a peak outside the original height profile, a window opens. You can select whether Vissim should insert an additional point at the beginning and end of the link 10 cm before the last point each and run the calculation again.

The course of the road is adjusted.

Tip: Alternatively, you use Recalculate spline to select the desired links or connectors and then press Ctrl+R.
