When you add an
overlay to a
project from the
Image Tab, On-Screen
Takeoff makes a copy of that
overlay file and places it in an "
Overlay" folder in the "
Image Folder" as indicated on the
Cover Sheet. Any alignment or resizing changes are made directly to that copy.
If you add an
Overlay via the
Cover Sheet, you bypass that copy creation process. Any alignment/resizing done to the
Overlay would affect the "Base
Image" on another Page because the changes are being made directly to the
Image file, not a copy. If you've used this file as the Base
Image or
Overlay on another Page, you will be resizing/aligning it anywhere it is used which may cause
takeoff to no longer match the plans. It's best to add Overlays via the
Image Tab unless it is necessary to use the
Cover Sheet method. If you do use the
Cover Sheet method, make a copy of every file you are going to use as an
overlay, put it in an "Overlays" folder (where the original files are stored), and then use those Copies as Overlays.
