A Foreman (or Foremen), a user with a dpc-foreman license only, can only view the Base Image on any page. This is by design to make the program easier for the Foreman to use. The Foreman only needs to understand the actual final building plans, so there is no reason for them to see incremental changes made before work began.
If you have performed takeoff on an Overlay, you will have to swap that overlay with the base image for that page (see the On-Screen Takeoff User Guide for instructions on image/plan management).
For the Foremen to view the correct (current, latest) plan, that plan must be set as the Base Image before the Project Manager sends the DPC Bid Package to the field.
