Design a vertical alignment with Draw Profile command.
Click on Draw Profile command.
Vertical alignment can be drawn by selecting vertex points in the drawing.
Tangents can be inserted into the profile by selecting vertex points with a mouse. Alternatively, they can be inserted by selecting parameters in a dialog box that appears after the definition of the first tangent point in the drawing.
A dialog box with tangent parameters appears.
In the first example, user can barely control their values, while in the second one they can precisely define station, elevation, distance, slope and section of the next vertex point.
Press Enter to finish.
A warning message about the minimum allowed vertical-curve radius can appear.
