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.
