The Profile dialog draws a profile showing Elevations, Distances and Grades for a Path on the layout.
Choose a Path by Left-Clicking on End-Points. As each End-Point is chosen, the Path is extended via the shortest route. Selecting the end of the Path trims the Path back to a last Defined Elevation point (if any, otherwise the Path is cleared).
If no route is possible an error message is displayed. There are several reasons why this might happen:
The Path is drawn in the Profile Color (default Purple) on the Layout.
If the shortest Path is not what you want, you can choose End-Points that are closer to the end of the Path. Also, you can Ignore End-Points to prevent the Path from choosing a route through that End-Point. Shift-Right-Click displays a popup-menu that allows you to change the specified End-Point to be a Defined, Ignored or None Elevation End-Point.
Each Defined Elevation End-Point on the Path is drawn as a Vertical bar, labeled with its height and distance from the beginning of the Path.
The Grade between points is displayed between the Vertical bars. The Grade line is drawn in Blue if that portion of the Path does not contain more than one Shortest Path between Defined Elevation End-Points. Otherwise it is drawn in Red, to indicate the grade is an average and the actual grade may vary for any particular track segment. See Computing Dynamic Elevation for more details.
Stations on the Path are displayed along the bottom of the Profile.
You can change the heights of Defined Elevations by Left-Dragging on the Profile Window. As you Drag, the new Elevation and Grades to each side are displayed at the bottom of the Profile dialog.
The Done button closes the dialog.
The Clear button removes all points from the Path.
The Print button prints the dialog. The aspect ratio is preserved on the print-out. You will probably want to print in Landscape format.
