3. Type the name of the road or trail you want to add in the Road/Trail Name text
box.
Name each routable road/trail you add so you can locate it using the find feature.
4. Hover the mouse pointer over existing roads and trails to display the yellow diamond
symbol . The yellow diamond symbol indicates where on an existing road the point
for your new road will connect (connection point).
Notes
• The new road must connect to an existing non-limited access road for routing
to occur on the new road.
• Each time you intersect an existing road or trail, hover the mouse over the
road/trail to display the yellow diamond symbol and click to create a
connection point before continuing to draw. If you draw the line over the
road/trail without creating a connection point, routing cannot occur along the
intersection.
5. Once you locate the connection point for your new road or trail, click the map to
place the first point. Click point-to-point or drag to add the new road/trail to the
draw layer.
The following information is available as you add each point in your road or trail:
• The coordinates of each point display in the corresponding text boxes.
• The distance and bearing/angle of each new point from its previous point
display in the corresponding text boxes.
6. To finish the line draw for the new road or trail, enter the last point on the map
screen and click Done.
The new road or trail displays on the map with the name you typed in the Road/Trail
Name text box.
You can also finish the line draw by pressing the ENTER key on your keyboard or
double-clicking while entering the last point of the line.
Drawing a Line, Arc, or Spline on the Map
You can add lines, arcs, and splines to a draw file and adjust their line style, color, width,
and display them with map line features.
• Use lines to mark boundaries or to add railroads or utility lines. You can draw lines
with varied line styles, weights, and colors, including lines that reflect actual map
line types.
• Use arcs to add curved line features to a draw file. You can draw arcs with varied
line styles, weights, and colors, including lines that reflect actual map line types.
Note An arc is created by entering only three points on the map. The first and
second points determine the distance of the first arc base from the last arc base. The
third point, placed between the first two, determines the radius of the arc and fixes
the arc in place.
• Use splines to add trails or any other map feature that contains curves. You can
draw splines with varied line colors, weights, and styles, including lines that reflect
actual map line types.
Note As you draw a spline, points are entered in much the same way as those
entered when creating a line. The difference between a line and a spline is that when
you enter each point, the line segment between the points curves instead of staying
straight.
