Selecting vector profiles

If a vector is not selected, a simple line is automatically generated and used to calculate the profile. As an alternative, you can create a vector or select an existing vector for the profile. To modify the profile vector, use the Line Color editor or Vector Editing toolbar.

Draw or select an existing vector layer.
With either the Selection Tool cursor or the Vector Editing cursor, select the line in the view pane. The values change in the Profile Table and the line is updated in the Profile Graph.
