When the 45-degree route direction is set in the active style, the Angle Control can be displayed in 3D Orthogonal Route. When it displays, you can rotate the route position in 45-degree increments.
To use the Angle Control, click the arrow pointing in the angular position you need. When you are satisfied with the position, select a point on the line to create a segment at the new angular position.
Click an arrow to direct the path to the angle you want.
The route path changes to the new angular position. If you select the wrong direction, click the single arrow displayed on the selected axis to revert to the previous angular position.
