Is there a way to copy and import drawings with takeoffs marked, from one ZZ 'project' to another?
If I make two files of the same project and want to merge, is this possible?
Not that I know of and its not needed from my point of view. Since mutiple users can be in the same file you can use layers to have seperate bucket of markups and takeoffs for everyone.
Watch the multiuser and layer tips vid I made for a few pointers.....worth 10min of your time. LINK
Oh an I hope your sitting down when you watch this one!

Hi, currently we do not support merging projects together, however we do support copy and paste across projects.
