A region is a primitive design object. As well as the standard region that is used for design tasks, there is a second type of region available, referred to as a region keepout. A region keepout can be placed as a layer-specific keepout object or an all-layer keepout to act, for example, as a placement or routing barrier. The difference between a standard region and a keepout region is that layer-specific keepout-type fills are not included in output generation, such as Gerber or ODB++. A keepout region is identified by having an outline in the Keepout color.
Region Keepouts are available for placement in both PCB and PCB Library editors in the following ways:
After launching the command, the cursor will change to a cross-hair and you will enter region keepout placement mode. Placement is made by performing the following sequence of actions:
Additional actions that can be performed during placement while the region keepout is still floating on the cursor and before the first corner of the region keepout is anchored are:
This method of editing allows you to select a placed object directly in the workspace and graphically change its size, shape or location.
Region Keepouts contain two points, or "handles", with which to edit the shape of the region.
An existing region keepout can be re-shaped by moving these handles, or vertices, located at each corner or at the center of each edge.
To modify the region keepout shape:
In addition to vertex editing, you also can use the Modify Region Border command to easily change the shape of polygons. The command is run by right-clicking on the desired polygon then selecting Polygon Actions » Modify Polygon Border. Once the command is launched, the cursor becomes a crosshair. Each time you click, a new vertex is added. As during region keepout placement, the Shift+Spacebar shortcuts can be used to change corner shapes.
The following methods of non-graphical editing are available:

The properties of a Region Keepout can be edited in the PCB editor's Properties panel, which allows editing of all item(s) currently selected in the workspace.
During placement, the panel can be accessed by pressing the Tab key.
To access the properties of a placed Region Keepout:
The List panel allows you to display design objects from one or more documents in tabular format, enabling quick inspection and modification of object attributes. Used in conjunction with appropriate filtering - by using the applicable Filter panel, or the Find Similar Objects dialog - it enables the display of just those objects falling under the scope of the active filter – allowing you to target and edit multiple design objects with greater accuracy and efficiency.
