Geo - Rotate Nodes Along Links layout algorithm properties

When the Geo - Rotate Nodes Along Links schematic layout algorithm is chosen in the Layout Task drop-down list, clicking the Layout Algorithm Properties button Layout Algorithm Properties icon on the Schematic Editor toolbar opens its associated properties dialog box as follows:

The parameter values are either those specified by default by ArcGIS Schematics or those specifically set as the default for the schematic diagram template related to the active diagram using the Schematic Dataset Editor Layout Task tab for this schematic diagram template.

VorsichtVorsicht:

The rotation angle computed during the algorithm execution is stored in the ROTATION field of each schematic feature class that implements the nodes in the schematic diagram. This ROTATION field must be turned on to symbolize the schematic nodes so they automatically rotate according to the computed angle values. In ArcMap, on the Layer Properties dialog box related to the desired node feature layer, you must click the Advanced button and click Rotation, then from the Rotate dialog box that opens, choose ROTATION in the Rotate Points by Angle text box. You also need to check the Arithmetic option so the assigned symbol is rotated as expected—that is, from east in a counterclockwise direction.

Flow directed check box

Check the Flow directed check box if you want the node symbols to rotate according to the flow direction defined for the schematic links contained in the diagram. This check box is unchecked by default unless it has been specifically checked for the diagram template related to the active diagram.

The figures below show the Flow directed check box:

Angle offset parameter

The Angle offset parameter specifies the rotation angle—in degrees—which is also automatically applied to the node symbols.

The figures below show the Rotate Nodes Along Links layout results with different angle offset values. The Flow directed check box is also checked for the algorithm execution.

Automatically applied check box

Check the Automatically applied check box if you want the Rotate Nodes Along Links function to automatically execute each time schematic features are moved in the diagram by end-user manipulation or schematic algorithm execution.

VorsichtVorsicht:

The Rotate Nodes Along Links layout algorithm must be executed once with the Automatically applied check box checked for the algorithm to be automatically applied each time schematic features are moved.

Restore Defaults button

Click the Restore Defaults button to reinitialize all the Rotate Nodes Along Links parameters with their default values. The restored values are either those specified by default by Schematics or those specifically set as the default for the schematic diagram template related to the active diagram using the Schematic Dataset Editor Layout Task tab for this schematic diagram template.
