Constrain a z-enabled segment vertical

When you create z-enabled 3D polyline features in a scene and right-click the map, Vertical Vertical appears on the context menu. This command locks the direction of new z-enabled line segments vertical along the z-axis.

For steps to specify z-values using the elevation tools on the Edit tab using tools in the Elevation group, see Specify an elevation for 3D features.


To constrain a new z-enabled segment vertical, create at least one vertex, right-click the map, and click Vertical Vertical. To remove the constraint, press the Esc key.
