Software That Opens & Edits IFC Files (5 Tools, 2026)

IFC is the open BIM data standard maintained by buildingSMART International. Where DWG carries lines and STEP carries solids, IFC carries semantically-rich building models — walls know they are walls, doors know they are doors, slabs reference their floor level. This makes IFC the cornerstone of BIM-to-BIM interoperability and the required format for openBIM submissions to governments and large-firm collaboration. IFC4 is the current production version; IFC4.3 adds infrastructure (roads, rails, bridges) support.
