**A shapefile stores nontopological geometry and attribute information for the spatial
features in a data set. The geometry for a feature is stored as a shape comprising a set of
vector coordinates.... This feature is most commonly used for roads in GRLevelx products**
Along the Main Menu select the "GIS" tab.
Click on "Load Shapefile"
Select the correct Shape and Style files from your documents and click Import.
Make sure "Show Shapefiles" is checked.
You can always unload the Shapefiles by selecting "Unload Shapefiles". This is done on a per shapefile basis so this will NOT unload all your previous shapefiles.
