Use the profile layout tools to edit curves, tangents, and points of vertical intersection (PVIs) on layout profiles.
You can edit a layout profile by manipulating grips or by entering specific values that reflect road design criteria.
Selecting either the 
PVI Based or 
Entity Based button on the Profile Layout Tools toolbar has three effects:
- Updates the tools available on the Profile Layout Tools toolbar
- Changes the data shown in the Profile Entities vista
- Changes the data shown in the Profile Layout Parameters Dialog Box
For information on profile tools for creating and editing profiles, specifying curve settings, and displaying the profile editors, see Profile Layout Tools.
You can use transparent commands when you are prompted to specify direction, radius, or length, or use station offsets to specify any points. For more information, see Transparent Commands.
