Control Description
Mode Select one of the following modes for creating curves:
  • Circular Curve
  • Grade
  • Parabola
  • Parabola (Asymmetric)
Vertical Intersection Point Input a vertical intersection Point.
Note:
  • Vertical intersection points at the start and end of the long section cannot be modified.
Arc Component Select one of the following:
  • Curve Length - Input the Length of the circular arc or parabola.
  • Radius - Type the radius for the circular arc.
  • K-Value - Type the K-value for the parabola.
Curve Length In: Type the length of the entry curve for a asymmetric parabola.
Curve Length Out: Type the length of the exit curve for a asymmetric parabola.
Notes
  • Click Solve to preview the curve in the long section view.
  • Click OK to insert the curve.
  • Select the Mode 'Grade', to remove a curve from a vertical intersection point. The curve is removed automatically when a vertical intersection point is picked.
  • If a curve with the specified parameters cannot be fit to the Vertical Intersection Point, the point will display as a grade point. Select the point in the long section view and edit the curve parameters in the Attributes tool window.
