Clash check and revision comparePRO

Load the architecture and the services together and find where they clash: hard clashes between two models or two IFC classes, with a tolerance, each one ready to zoom to and export as a BCF issue. When the next issue of a model arrives, Compare shows what was added, removed or changed.

How it works

Step by step

1

Load the models

Open the first model, then Add a model in the Models tab. Two models together are free; BIM Explorer Pro loads as many as you need.

2

Choose the sets

In Checks, under Clash check, choose Set A and Set B: a model, an IFC class, or both.

3

Set a tolerance

Overlaps smaller than the tolerance (in mm) are ignored. Then Run clash check.

4

Review and share

Click a clash to select both elements and zoom to them. Export the clashes as CSV, or as BCF issues with a viewpoint each.

5

Compare issues

When a new issue of the model arrives, open Compare and choose the revised IFC. See what was added, removed or changed before you update the BOQ.

Help: IDS and clash checks has every option in detail.

Frequently asked questions

What kind of clashes does it find?

Hard clashes: elements that overlap. It checks bounding boxes first, then the meshes themselves, so a duct buried inside a wall still counts. The depth shown is approximate.

Can it check clearances?

Not yet - it finds overlaps, with a tolerance for small ones.

Can I send clashes to other tools?

Yes. Export them as BCF issues (one per clash, each with a viewpoint) for any BCF tool, or as CSV.

Is it free?

Clash check and Compare are part of BIM Explorer Pro (a one-off £29.99, free 7-day trial).
