Real-Time Collaboration

HVAKR projects are multiplayer. Several people can open the same project at once, and every change syncs to everyone in real time.

How It Works

Live Sync

HVAKR saves and syncs as you work:

• Edits appear for other collaborators within moments — there’s no manual save or refresh
• Changes are written field by field, so teammates editing different things don’t overwrite each other
• If two people change the same field at the same time, the most recent edit wins

Use Undo / Redo in the toolbar to step back through your own changes.

Presence

The top toolbar shows an avatar for each collaborator:

• People currently in the project show a green dot; everyone else is dimmed and sorted after them
• Hover an avatar to see the person’s name; when there are many collaborators, the extras collapse into a +N badge
• Click the avatars to open the Share panel

Live Cursors

You can watch teammates’ cursors move around the project. This is off by default, and each person turns it on for themselves:

1. Open the account menu (your avatar, top-right of the toolbar)
2. Click Realtime Cursors to toggle it on

Once on, every collaborator viewing the same screen appears as a colored cursor labeled with their name. Cursors are scoped to the current view — you see the cursors of people looking at the same page you are.

Chat & Comments

The Chat button in the toolbar opens a shared conversation for the project. A badge shows how many messages you haven’t read yet.

• Message your team — type in the composer and send; messages are grouped by day, and you can search past messages
• @mention — mention a teammate to loop them in; mentioning someone who isn’t on the project yet prompts you to invite them
• Comment on an element — open the context menu for a space, zone, or system (right-click it on the canvas) and choose Add Comment to open Chat with that item attached; the composer notes which item you’re commenting on
• Reply in threads — reply under a message to keep a discussion together

Best Practices

Divide the Work

To stay out of each other’s way:

1. Split work by area — different floors, zones, or systems
2. Use Chat to say what you’re working on
3. Attach comments to the specific space, zone, or system in question

If Your Connection Drops

If your browser goes offline, HVAKR shows a Connection Lost dialog and pauses editing — it doesn’t store offline edits, so there’s nothing to sync on reconnect. When your connection returns, the dialog clears and a Connection restored message appears; if it doesn’t, click Refresh to reload the page.
