Clash Detection

Check coordination risk in the model context

IFC clash detection helps reviewers find where selected model sets conflict or fall inside a required clearance. In IFC Viewer, the Clash Detection Pro Tool focuses on hard-clash, minimum-distance and configurable-clearance workflows for IFC coordination review.

The page does not describe a cloud coordination platform or an automatic design approval system. It describes a local review workflow for inspecting reported findings and deciding what needs coordination attention.

What you can review

Use the tool to run the supported clash or clearance workflow, inspect the evidence behind each finding and keep the result tied to the model context that produced it. Findings can support a wider coordination conversation, especially where BCF issue workflows are used alongside model review.

The usefulness of any clash review depends on the selected model sets, model quality and the clearance rules configured for the review.

How it fits with federation and issues

Federated IFC review helps bring disciplines together before checking interactions. BCF issue tracking then gives teams a structured way to carry relevant findings into an issue workflow where supported. Clash Detection sits between those tasks: it helps identify the coordination item before the team decides how to manage it.
