Generating a spline

In the Network editor, you can insert a desired number of intermediate points into a link or connector. You can also do so between existing intermediate points.

You can convert the link, connector or a section of it into a spline. This allows you to create a more harmonious curve.

After changes on the curve, select Recalculate Spline to re-establish a more harmonious curve (Recalculating the spline).

Creating a spline based on the entire link

1.  On the network object sidebar, click Links.

2.  In the Network editor, right-click desired link or connector.

3.  On the shortcut menu, click Generate Spline.

The Generate Spline window opens.

4.  Make the desired changes:

Element	Description
Intermediate points per segment	Enter the number of intermediate points to insert. Default value 3
Keep current intermediate points	Select this option to insert intermediate points in addition to the the existing points.

Intermediate points are inserted into the link or connector. If the link contains multiple intermediate points, several new intermediate points are inserted in between the existing ones. You can move the intermediate points to model the course of the link.

Adding new intermediate points up to the desired point

1.  On the network object sidebar, click Links.

2.  In the Network editor, click the link or connector of your choice.

3.  Press the Alt key and hold down the left mouse button. Drag the mouse pointer to the intermediate point up to which you want to insert additional intermediate points or until the end point of the link or connector.

The intermediate points are highlighted. A highlighted line connects the intermediate points.

4.  Release the keys.

The Generate Spline window opens.

5.  Make the desired changes:

Element	Description
Intermediate points per segment	Enter the number of intermediate points to insert. Default value 3
