begin by loading that plot file. Run the Exporter and then
select the "File ->Open" option from the menu bar. Select the
plot file for the cave you are working with.
In this case we will be working with Fulford Cave,
like we have done for the other tutorials. (There is a copy of
the Fulford data in the Compass distribution.)
After you open the file, an image of the SVG map will appear
in the center of the program. The image to the right show what
the Fulford map looks like after it has been loaded.
