Allows the route boundary to be changed by clicking any two points along the route boundary. You can change the selected portion into a Corner shape (default option), an Arc (select in the dialog box or press CTRL), or select Pick Element in the dialog box and then pick an element in the drawing. Continue picking boundary two points at a time to change the boundary as desired or right-click to finish editing.
The options to change the route are to either draw the selected route boundary as a Corner/Arc or to replace it with a picked element.
Draw as:
Corner - move the pointer to adjust the corner size and then click to draw.
Arc - move the pointer to adjust the arc size and then click to draw. Alternatively, press CTRL on the keyboard to select this option.
Pick Element - pick an element in the drawing
