Setting the Scale of an Image
Setting the scale for each page in a project before starting takeoff is of utmost importance. Even though the page may indicate a particular scale, it's important to verify that this is accurate. A small discrepancy in the scale of a displayed image can greatly affect takeoff quantities.

If there are several regions on a particular page that are drawn to different scales, that page will need to be duplicated for each change in scale. There are two ways to set the scale of an image (see Adding (Linking) Images to a Bid for more information):

WARNING: Changing the scale of a page after performing takeoff is not recommended as On-Screen Takeoff may not be able to resize all takeoff correctly. Some takeoff may no longer be visible on the page and or resized incorrectly. |
