The original CF2 footprint is copied, and then we trace a new section that should be deleted or adjusted against the updated green outline. If the footing is no longer needed, that CF2 instance can be made negative so the net length becomes positive minus negative, like 55 minus 15 to get a 40 net value. This nets out to credits or negative yardage in the estimate. I am not asking you for specific action yet.
