You must select the Lock K radio button to use this control.
Defines curvature in project units per %. For example, if K=10.0, then every 10m (or ft.) the grade will change by 1.0%. When you change K, the Length and IP and Tangent Parameters update instantly. If the curve does not fit the available tangents, the Apply button will be disabled and a warning will be reported.
You must select the Lock L radio button to use this control.
Allows you to change the length of the curve. When you change Length, the K and Tangent Parameters update instantly. If the curve does not fit the available tangents, the apply button will be disabled and a warning will be reported.
These radio buttons define whether a curve exists.
Select Parabola (the only type of curve supported) to define a curve and to enable the other curve parameter controls.
Select No Curve to remove a curve and to disable the other curve parameter controls.
Saves changes to the above values, and updates alignment and all windows to show the result.
If the Apply button is not available, it means one of two things:
1 The curve has not been changed from the one already
applied.
2 The curve can't be applied to the current alignment. In this
event the reason will be reported left of the Apply button; for example
"Curve does not fit tangents".
Previous Curve, Next Curve Moves the current selection to the previous or next IP or curve along the vertical alignment. Any changes made to the current curve or IP are lost unless you have Applied them.
Note that when a curve is selected, the Current Point displayed in the other windows is the EC (End Curve) point.
Road Class ParametersThis button pops up the Road Class Specifications Dialog.
Set/Get Default CurveThe first button saves the parameters for the current curve as the new Default Curve.
The second button retrieves the Default Curve parameters. Once your Default Curve is defined, creating a new curve requires two button clicks: Get Default Curve and Apply.
Default Curves (Vertical and Horizontal) are saved with your template table; they are saved with your document and can also be saved externally in a TPL file. Open and update your standard template table files (Normal.tpl and possibly others) to make default curves available in new projects.

If a curve is not defined, they show the coordinates of the previous, current and next IPs.
They also show the incoming and outgoing grades.
