When you upload a sheet with the same number as a sheet already in the project, RedTeam Flex treats it as a revision. Publishing it creates a new version and adds it to an addendum for you.
How automatic addendums work
While you review an upload, a note tells you when a sheet number already exists. For example: "A-201 already exists. Publishing creates v2 and files it under a new addendum."
When you publish, the sheet becomes the next version (for example, v2) and is added to a new addendum automatically. The Plans list shows the latest version.
If the sheet isn't a revision, change its sheet number before you publish. It's then added as a new sheet.
To add sheets to an addendum yourself, use Add to Addendum on the review screen. See RedTeam Flex - New Plans & Specs: Reviewing, Rescanning and Publishing Plans.
View addendums
Open the Addendums tab. Addendums created automatically are named after the upload, for example Upload - A-101 - 10/29/2026.
Click the arrow next to an addendum to see its sheets and which version each one supersedes.
Click the download button next to a sheet to download it.
