The Check In Region Button: Check Objects

When the Check In Region button in the DRC Menu is active, design rule checking is performed on objects the user clicks on or drags over. The method of selecting a region to check is the same as for the Check In Foreground command, however the Enter key is ignored. Violating objects are marked, the error region highlighted, and a pop-up explains the error. No file is produced. A maximum of 15 errors are accumulated for each region -- the check terminates at this error count. The Check In Region command button remains active until explicitly terminated, unlike the Check In Foreground command.
