Does Nira support IFC files?

Yes. Upload an .ifc file the same way you upload any other asset, and Nira builds it into a 3D asset with its object hierarchy available in the Layers panel. .stp, .step and .p21 CAD files work the same way.

IFC and CAD uploads are available on all current plans. Organisations on a legacy Core or Business plan need to upgrade first; reach out if you have questions.
