Steps to Add/Create a Polygon Shapefile
Adjust the map window view so that it shows a view where polygons are to be placed. A single polygon or multi-polygon shapefile can be created.
With the mouse in Select Mode, click GISTools>Add Shapes>Polygons -- this starts the process. To end the process, this same menu item will be clicked ending the process as described below.
At start-up, when GISTools>Add Shapes>Polygons is clicked, you are prompted for the file name to be created. The default name is c:\cvgis\1\$$polygons1.shp. Use that file by clicking the Open button on the New shapefile name dialog. The file must not be in use and will be overwritten if it exists.
A message appears "New polygons layer created; make active; click to add points." Click OK. To make the new polygon layer active, click the layer name once as shown below. The layer name turns blue indicating this is the active layer.
