Add a floating vertical curve by specifying a pass-through point and a parameter.
The illustration shows a floating curve from an existing entity (1) to a pass-through point (2) and a minimum radius (3). This curve type can also be drawn from a specified K value.
To add a floating vertical curve with a pass-through point and a parameter
- Click the profile. Click Profile tab
Modify Profile panelGeometry Editor
. - On the Profile Layout Tools toolbar, click
Floating Vertical Curve (Parameter, Through Point). - Select the fixed or floating entity to which you want to attach the curve.
- Do one of the following:
- To specify a K value, enter the K value.
- To specify a minimum radius for the curve parabola, enter R (radius), and then specify the radius.
NoteIf the profile was created using the criteria-based design feature, a default value is displayed on the command line. Minimum K values at given design speeds are specified in the design criteria file . Minimum curve length and radius are calculated from the minimum K value at the current design speed.
- Specify a pass-through point.
- If selected a parabola in step 5, specify whether the resulting curve should be either a crest or sag.
