Draw Regions

Select a region shape (rectangle, circle, ellipse, polygon, point) from the shapes panel and draw regions as follows

To define a point inside an existing region, click inside the region to select it (if not already selected), now press left mouse button, drag and release to draw region inside existing region.

To draw a region inside existing region, click inside the region to select it (if not already selected), now click again to define the point.

To select, click on (or near) the existing point.

Polygon and Polyline

Press [Enter] to finish drawing the region or press [Esc] to cancel.

If the first vertex needs to be defined inside an existing region, click inside the region to select it (if not already selected), now click again to define the vertex.

To select, click inside the region. If the click point contains multiple regions, then clicking multiple times at that location shuffles selection through those regions.
