Creating Clip Regions in MapInfo Pro

Products affected: MapInfo Pro™
A clip region allows a MapInfo Pro user to select an object or objects and then display only those objects and those map objects from other layers in that specific mapper only.

Here is a mapper consisting of a USA table, a Bing Roads layer and a points layer called USCTY153:

Uses can toggle the Clip Region on and off using Clip Region On/Off switch found at the "set Clip Region" drop-down.
The Clip Region is mapper-specific so other mappers are not affected by this procedure.
If the user uses the "Clone View" feature (Home > Wnidows > New Document > Clone Window), the new mapper will inherit the Clip Region.

If the user wishes to define a different Clip Region in a mapper, simply turn off the Clip Region , select a new map object and choose "Set Clip Region" again and select "Replace" at the appropriate dialog:
