Use horizontal manipulators to edit the horizontal geometry of design roads. To use horizontal manipulators, you must display the road in plan view.
To use vertical manipulators, you must pitch the model and view the design road at an angle.
| Endpoint moves the start or end point of a road. When the endpoint grip is moved, the elevation adjusts to match the existing ground. |
 |
| Midpoint moves a tangent. |
 |
| Point of Tangency modifies the start or end point of a curve. This manipulator affects the curve length and radius. |
 |
| Curve Radius modifies the radius of a curve. |
 |
| Point of Intersection (PI) moves the point at which two tangents intersect. |
