Audit a model before it goes out

Run the checks that catch a bad model before a client or a site team opens it: coordinate base, live clashes and classification completeness.

How it works, step by step

3 steps across the platform - what you do at each one, and why it matters.

1

Check the coordinate base

Federations

Confirm the model sits on the shared project origin and grid before anyone downstream measures or clashes against it.

Why: A model that is a few centimetres off the shared base silently corrupts every clash test and quantity taken from it later.

2

Run a clash pass as a quality check

Clash detection

Run the clash test as a final quality gate rather than a coordination exercise, looking specifically for gross geometry errors rather than genuine trade conflicts.

Why: A clash run at issue time catches a model with parts floating in space or duplicated by accident, the kind of error a design review alone can miss.

3

Confirm classification is complete

Validation

Run the validation rules and confirm every element carries the classification and property set the next stage expects, with no unmapped category left behind.

Why: A model with a gap in its classification hands the next user, an estimator or a contractor, an element they cannot price or schedule without asking you first.
