Some of the people whose clashes you are working don't have a ClashWise account — a subcontractor, a specialist, the person who actually owns the ductwork. You can hand one of them a lane for the length of the meeting, with a link, and no account.
They see their lane. They can work it. They see nothing else.
What you need first
- A live session with the room split by responsible contact. A guest pass is that contact's assignment, so only a contact lane can be given away — a lane dealt out by level or discipline has nobody attached to it, and the Invite button doesn't appear on one.
- The contact must have an email address in your clash matrix. That's who the pass is for, and it's the name the room sees.
- You must be the coordinator who started the session, or whoever holds the wheel.
Sending the invite
On the coverage board, the eligible lanes carry an Invite button. Click it and ClashWise mints a pass and shows you the link, with the guest's name and the lane it covers.
Copy the link and send it to them yourself — in the chat you're already in, or by email. ClashWise does not send it for you. That's deliberate: mid-meeting the link is going into the Teams chat regardless of what an email would do.
The lane is handed over the moment you invite. It shows the guest's name on the board for everyone.
What the link is
The link is the credential. There is no password and no code, so:
- Anyone holding the link can use it. Treat it like a door key: send it to the person it names, not to a group channel you don't control.
- It is shown once. ClashWise doesn't keep a copy you can go back and read. If you lose it, invite again — which mints a fresh link and revokes the old one.
- It dies with the session. Ending the session revokes every pass on it immediately. A pass also expires on its own after twelve hours if the meeting is abandoned.
What a guest can do
A guest is a real participant in their lane, not a spectator:
- See the clashes on their lane in the 3D viewer, and nothing else in the set.
- Set a clash's priority and status.
- Mark clashes reviewed.
- Flag a clash for discussion, so it lands on the room's agenda at Regroup.
- Take the wheel and lead the walkthrough, like anyone else in the room.
- Appear on the roster with their name, and point at the model.
Everything they do is recorded to the session exactly as a member's edits are, with their name against it, and flows into the minutes and the PDF.
What a guest cannot do
Everything else. The pass opens their lane and nothing more — they cannot reach the rest of the clash set, other sessions, your organization, reports, exports, the AI, or any part of the API. Reassigning their lane to someone else cuts their access off, mid-meeting, without you having to revoke anything.
They also cannot change a clash's responsible contact, which would move work off their own lane or pull someone else's onto it.
Re-inviting
Invite again on a lane a guest already holds and the button reads Re-invite. It mints a new link, revokes the previous one, and removes whoever was holding it from the room. Use it if a link went to the wrong person, or the right person lost it.
Limits
A session holds a limited number of guests at once, and your organization has a monthly allowance for passes. You'll be told as you approach the monthly figure rather than at the moment it stops you, and the message names the actual number. Guests are not seats: inviting someone to a lane never consumes a licence, and a guest cannot substitute for a member.
Tips
- Invite at the point you split, not when you reach their clashes — a guest who arrives at the start has the whole parallel stretch to work in.
- Send the link in a direct message, not a channel. It's a key.
- Check the board for their avatar before assuming they joined; a link sent is not a person present.
- If someone needs more than their lane, they need an account, not a wider pass. That's the boundary the pass exists to hold.
FAQs
Does the guest need to install anything or sign up? No. They open the link in a browser and they're in the room.
Can I invite someone who isn't in my clash matrix? Not with a pass. The pass is scoped to a matrix contact's clashes, so the person has to be one of those contacts with an email address. Add them to the matrix first.
What happens to their work when the session ends? It stays. Everything a guest recorded belongs to the clash set exactly like a member's edits — the session ends, their access ends, the work remains.
Can two guests share one lane? No. Inviting a second person to the same lane replaces the first.
Why is there no Invite button on my lanes? Either the room was split by something other than responsible contact, or you're not the coordinator or the driver. Both are shown on the session bar.
