Generating a spline

You can insert new intermediate points, select existing intermediate points, insert additional intermediate points later in a link or connector in the network editor.

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
Spline 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.

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

Selecting spline points, inserting new spline points and generating a spline

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 spline point up to which you want to insert additional spline points or until the end point of the link or the connector.

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

4.  Release the keys.

The Generate Spline window opens.

5.  Make the desired changes:

Element	Description
Spline 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.

The intermediate points are inserted into the link or connector. If you have highlighted several successive sections of a link, new points are inserted into each section. You can move the spline points to model the course of the link.

Only Generate Spline between Adjacent Points

1.  On the network object sidebar, click Links.

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

3.  On the link, right-click the desired intermediate point.

4.  On the shortcut menu, click Generate Spline For Adjacent Sections.

The Generate Spline window opens.

5.  Make the desired changes:

Element	Description
Spline 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.

The intermediate or spline points are inserted into the link or connector between the point selected and its adjacent point. You can move the spline points to model the course of the link.
