When you use the Vector tool in the Tools toolbar to draw a line or shape on the screen, it creates a Polygon. This polygon has its own properties dialog box containing three tabs:
General – this tab contains the name of the polygon, its size and position on the page.
Vector Pen – this tab contains the Pen properties of the vector i.e. the line or outline of a vector.
Vector Fill – this tab contains the Fill properties of the vector i.e. the fill colour of the vector.
In the Objects tab of the Organiser, select the Vector object on the page and click on the 
symbol to show all of the polygons that make up the Vector object.
Select the name of the polygon in the Vector object that you want to open the Properties dialog for and right-click to open the right-click menu. Select Properties from the right-click menu – this will open the Polygon Properties dialog.
