Work together
Share a project, edit it at the same time as your team, see who is working where and save versions you can return to.
Edit at the same time
Everyone in the project sees changes as they happen. The faces at the top show who is here; their selections are outlined on the map and the Properties panel says who is editing an element. Click a face and choose Follow to see their view.
Your undo only takes back your own changes, never a colleague’s. When two people add an element with the same name, the later one is renamed and AIRVLO tells you.
If the connection drops, keep working: the header shows Offline with the number of changes waiting, and they are sent when you are back online.
Versions
Ctrl+S saves a named version, with an optional note. Versions… in the Save menu lists them: Saved versions are kept, Automatic ones are made every hour and thinned to one a day after 7 days.
Open shows an old version read-only. Restore — owner only — brings it back for everyone; the current state is kept as a version first.
