2.Press the Edit Points toolbar button Poly Edit Points Button. Small rectangular handles will be drawn at each vertex point of the polygon.
3.Click on any point handle in a sub-polygon to select it. The currently selected point is indicated by a solid filled handle. All the other points have hollow handles.
4.With a point in a sub-polygon selected you can:
delete the current sub-polygon by pressing the Delete Sub-polygon button Poly Delete Sub-polygon Button or the Ctrl+Shift+Delete key or
