IFC Coordinate Checker

Check IFC origins, units and placements before spatial inconsistencies complicate a coordination review. Inspect the reported coordinate findings and export them for further review.

An optional Pro Tool inside the Apple IFC Viewer app. This page is a product guide.

IFC coordinate, unit and placement review before coordination decisions.

Find coordinate issues before they spread

IFC Coordinate Checker reviews origins, units and placements so spatial inconsistencies can be seen before they complicate coordination. This matters when models are federated, compared or checked for clashes across disciplines.

The tool is for checking and reporting coordinate evidence. It is not a surveying certification workflow and does not claim to transform or correct geospatial data automatically.

What to review

Coordinate review can cover model origin, placement information, unit consistency and large-coordinate or offset symptoms where supported. Exported findings can then guide the coordination decision or the conversation with the model author.

Why it matters for openBIM

Poor coordinate consistency can make otherwise useful IFC models difficult to align. Checking coordinates before federation, clash review or revision comparison helps keep downstream evidence easier to trust.

Tool questions

Common review questions.

Can IFC Viewer fix my coordinates automatically?

This page describes checking and reporting. Do not treat it as a coordinate-correction or surveying tool.

Why check units as well as origin?

Units and placement both affect how a model is interpreted in context. A coordinate review should consider both where supported.

Which related tools matter most?

Federator, Clash Detection and Model Compare all benefit from clear coordinate and placement context.
