ZZ Revisions

Hey Team,

How are people handling drawing revisions within the same ZZ Takeoff project?

My current workflow is:

1. Complete the original takeoff.
2. Duplicate the entire ZZ project when a new drawing revision arrives.
3. Import the revised drawings into the duplicated project.
4. Copy/paste the existing takeoffs onto the new drawings.
5. Make the required changes.

I do it this way because I want to preserve the original takeoff exactly as it was, while also having a complete revised takeoff that I can compare against the previous version.

I know ZZ has revision functionality, but I haven’t used it much.

Can the revision workflow achieve the same thing inside one project?

Ideally I’d like something like:

• Project: 219 Fast Track
• Original drawings/takeoff preserved
• Rev1 drawings added/replaced
• Existing takeoffs carried across where possible
• Rev1 changes made without destroying Rev0
• Ability to switch between or compare previous and current revisions
• Previous quantities/takeoffs remain accessible for audit and variation comparison

If so, how are people setting this up?

Also, does ZZ preserve the same takeoff/object IDs when an existing takeoff is carried onto a revised drawing, or does the revision process create new objects/IDs?

I’m mainly trying to understand whether I can stop duplicating whole projects while still retaining a proper revision history and quantity delta trail.
