What is a draw file?
Imagine a draw file as a sheet of glass laying on top of your map. You can add various
objects to the draw file to help enhance or pinpoint specific areas on the map, but these
objects do not become part of the map. They exist in a draw file that overlays the map.
There are five different types of draw files: draw, road, trail, waypoint, and track. You can
create more than one draw file and overlay one on top of the other while still viewing the
map beneath. See Editing/Locking Draw Files .
When you clear or delete a draw file, the objects in the draw file do not display and are
deleted along with the draw file. When you create and save draw files, they are saved within
the current project.
Some additional draw file facts:
• A draw file is automatically generated the first time you add a draw object to the
map.
• As you create draw files, they are added to the current project.
• You can add draw files to multiple projects.
• You can control the creation of new draw files in the draw file editing area.
• Draw files are saved by default in C:\DeLorme Docs\Draw with the default name; for
example, DrawLayer#.an2, with # indicating the number order in which the file was
created. You can rename draw files to better identify your specific information. See
Creating a New Draw File.
• You can have multiple draw files displaying at once while working on your map. Work
can be done on one draw file at a time, while viewing other files beneath it. You can
select different draw files to be the active, editable file from within the Draw tab. For
more information, see Editing/Locking Draw Files.
• Draw files created in a particular project are displayed only if that project is currently
displaying. For example, if DrawLayer27 is created in a project named Yarmouth
Zoom 14 only, DrawLayer27 does not display if a project named Old Port is currently
displaying.
• Routable roads and routable trails are not tied to a project; they do not change even
when a project is changed.
What are draw objects?
Draw objects are those objects you add to a draw file with the tools provided in the Draw
tab. Draw objects consist of line, area, or point objects. You can copy, move, delete, and
add draw objects to other draw files and add them to another project.
• Line objects are those objects consisting of line segments and points, such as:
• Routable Roads
• Routable Trails
• Tracks
• Lines
• Arcs
• Splines
• Area objects are those objects consisting of one or more closed line objects, such as:
• Polygons
• Rectangles
• Circles
