Scheduling and Starting Sessions

You can plan a coordination session ahead of time or start one on the spot. Both happen from the clash set you want to review: every session is scoped to the clash set it was opened from.

Where to find the session controls

Open your clash set from Clash sets in the web app.
Click the Coordination button in the toolbar. A panel slides out on the right showing the set's sessions.
At the top of the panel you'll find Start now → and Schedule, plus a toggle between a list view and a calendar view of the set's sessions.

If no sessions exist yet, the panel reads "No sessions yet. Start one now or schedule one for later."

Scheduling a session for later

In the coordination panel, click Schedule. The Schedule a coordination session dialog opens — "Plan a coordination meeting on this clash set — pick a time, set an agenda, and list the people you expect."
Fill in the fields:
- Title — name the meeting, for example "MEP vs Structural — Level 3".
- Agenda / details — optional notes about what the meeting will cover.
- Date & time — when the session is planned.
- Duration (min) — from 15 to 480 minutes; the default is 60.
- Attendees — add rows with Name, Company, and Email, or click Add from clash matrix contacts to pull people straight from your clash matrix's contact list.
Save the dialog. The session appears in the panel (and in the sessions hub calendar) with a Scheduled status.

Scheduling does not start recording anything — it just puts the meeting on the books.

Managing a scheduled session

Open a scheduled session from the panel list to see its detail view. From there you can:

Start → — begin the session now.
Edit — change the title, agenda, time, duration, or attendees.
Cancel — call the meeting off.
Delete it entirely. You'll be asked to confirm: "Delete this session and its attachments? This can't be undone."

Note that decisions and action items cannot be added while a session is only Scheduled — they become editable once the session is Active (and remain editable after it has Ended).

Starting a session right away

In the coordination panel, click Start now → (or Start → on a scheduled session).
If the set holds a large number of clashes, a focus step appears first: What do you want to focus on? This lets the team narrow the review to a manageable slice — for example a specific group or filter — before the meeting starts. Pick your focus or continue with everything.
ClashWise creates the session and opens the 3D viewer, ready for the live review.

From this moment the session is Active: every status, priority, responsible-contact, or due-date edit anyone makes on the set's clashes is recorded to the session automatically. See the Running a Live Session article for what you can do while live.

One live session per clash set

Only one session can be live on a clash set at a time. If you try to start a second one, ClashWise refuses with "Couldn't start — one may already be in progress." End the running session first, or join it instead.

Rejoining a live session

If a session is already running on the set, the panel's start button becomes Rejoin live →, and inside the 3D viewer you can use Open in 3D → to jump back into the model. You can also join from the Coordination console dashboard: whenever a session is live, the LIVE COORDINATION banner lists it with an Open › link.

Tips

Give sessions specific titles ("MEP vs Structural — Level 3") — the title is what appears on banners, in the sessions hub, and at the top of the minutes.
Add attendees from your clash matrix contacts where possible, so names and companies stay consistent with the people responsible for resolving clashes.
Use the focus step on large sets. A session recorded against a focused slice produces tighter, more readable minutes.

Troubleshooting

"Couldn't start — one may already be in progress." — another session is live on this clash set. Open the coordination panel to find it, then rejoin it or end it before starting a new one.
Can't add decisions or action items to a scheduled session — this is by design. Start the session first; decisions and action items are editable only while a session is Active or after it has Ended.
