Add a free circular curve.
Specify a radius, length, or pass-through point to define the curve.
The illustration shows a circular curve at PVI 1, passing through point 2.
To add a free circular vertical curve
- Click the profile. Click Profile tab
Modify Profile panelGeometry Editor
. - On the Profile Layout Tools toolbar, click
Free Circular Curve (PVI Based). - In the profile view, select a location near the PVI to which you want to add a curve.
- Enter one of the following parameters to complete the curve definition:
- Radius: Enter R.
- Length: Enter L.
- Pass-Through Point: Enter P.
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.
