Generating a spline

In the Network editor, on a link or connector, you can select spline points, insert spline points and convert the link, connector or a section into a spline. This allows you to create a more harmonious curve. After further 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 objects toolbar, click Links.

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

3.  From the shortcut menu, choose Generate Spline.

The 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 objects toolbar, 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 Convert section to spline window opens.

5.  Make the desired changes:

Element	Description
Keep current intermediate points	Select this option to insert intermediate points in addition to the the existing points.
Number of interm. points (per segment)	Enter the number of intermediate 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 objects toolbar, click Links.

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

3.  In the link, right click the desired intermediate point.

4.  From the shortcut menu, choose Generate Spline For Adjacent Sections.

The Convert section to spline window opens.

5.  Make the desired changes:

Element	Description
Keep current intermediate points	Select this option to insert intermediate points in addition to the the existing points.
Number of interm. points (per segment)	Enter the number of intermediate 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.
