Full Query

After defining Where The First Object Matches option, the designer can manually create query filter in this area.

Constraints

Room Locked - Allows you to lock the room in its current position within the design, preventing accidental movement either manually or by the Autoplacers. If you attempt to move the room when it has been locked, a warning dialog will appear asking whether you wish to go ahead with the move. The locked status of the room remains in force after such a manual-override movement. Default is disabled.
Components Locked - allows you to lock the position of components arranged within, and associated to, the room. Default is disabled.
Define - Enables you to define the area and location of the room. After clicking, you will return to the main design window, the cursor will change to a cross-hair and you will essentially enter room placement mode. Define the rectangular or polygonal room as required and at the location required. The component membership for the room has to be defined afterwards, it is not created automatically if the room area is defined around placed components in the design.
X1/Y1 - Display the coordinates for the location of the lower-left corner of the room's bounding rectangle. These fields are non-editable - if placing the room from within the PCB Rules and Constraints Editor dialog, the Define button must be used.
X2/Y2 - Display the coordinates for the location of the upper-right corner of the room's bounding rectangle. These fields are non-editable - if placing the room from within the PCB Rules and Constraints Editor dialog, the Define button must be used.
Layer Drop-down List - Defines which layer the room can be placed on. (Default = Top Layer).
Confinement Drop-down List - Specifies whether the components targeted by the scope (Full Query) of the rule are to be kept inside the room or kept outside the room. (Default = Keep Objects Inside).
