Introduction to Clash Sets

What is a clash set?

A clash set is a cloud copy of clash results from your Navisworks document. After you run clash detection in Navisworks Clash Detective, the ClashWise plugin publishes the results you select to clashwise.ai as a clash set — including the clash data, viewpoint images, 3D captures, level and grid locations, and element properties.

ClashWise does not detect clashes. Navisworks detects them; ClashWise is where you manage, coordinate, and analyze them once they are published.

Why publish clash sets?

Once your clashes are in a clash set on the web, you and your team can:

• Analyze with AI and your clash matrix — AI applies your matrix rules to recommend a priority, status, and responsible contact for every clash.
• Triage and assign centrally — review clashes in a grid or in 3D, set statuses and priorities, assign responsible contacts, set due dates, add tags and comments.
• Collaborate — share the set with a project so teammates see the same live data, run coordination sessions, and share insight dashboards or 3D scenes with people outside ClashWise.
• Report — dashboards, insights, PDF clash reports, and Excel, CSV, and BCF exports.
• Close the loop — sync the decisions back into Navisworks so the model file itself carries the coordination outcomes.

Clash numbers

When you publish, every clash receives a permanent number within its set — clash #1, clash #2, and so on. These numbers never change, even as the set is updated, so they are the reliable way to refer to a clash in meetings, links, comments, and reports. Use the number, not the clash title, when you point a teammate at a specific clash.

Who can use this

Publishing, updating, and syncing clash sets require:

• A Clash Management subscription — the Pro or Business plan, or an active trial. The Starter plan covers AI clash naming only and does not include publishing.
• The ClashWise Full Suite plugin edition installed in Autodesk Navisworks Manage (2024–2027). The Starter plugin edition does not include the Clash Management tools.
• Being signed in to ClashWise inside Navisworks, with an internet connection.

The round trip

Clash sets follow a repeating lifecycle between Navisworks and the web:

1. Publish — send selected clash test results to the cloud as a new clash set. See "Publishing Clash Sets".
2. Analyze and manage on the web — AI analysis runs against your clash matrix; the team triages, assigns, comments, and tracks progress at https://clashwise.ai/my/clash-sets.
3. Update — after the model evolves and clash tests are re-run, push new and changed results into the same clash set instead of starting over. See "Updating Clash Sets".
4. Sync — pull the analyzed statuses, priorities, assignments, comments, and web-created groups back onto the matching clashes in Navisworks Clash Detective. See "Syncing Analyzed Clashes".

Then the cycle repeats for the next coordination round.

What appears on the web after publishing

A published clash set shows up under Clash Sets in your ClashWise account with:

• Every clash numbered (#1, #2, …) with its title, status, priority, and location (level and grid, where the model contains that information)
• Viewpoint images for each clash
• A 3D viewer showing the clashing elements — per clash and for groups — with optional ghosted context models around them
• Searchable element properties for advanced filtering
• AI analysis results once the set has been analyzed against a clash matrix

If you publish the set to a project, the project's members see it too; otherwise it is private to you.
