DeLorme Topo North America 10.0 User Manual page 187

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 features 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.

map. Labels display when end points are clicked if the Show Measurement check box
