Industry body buildingSMART UK has reported a measurable uptick in IFC 4.3 adoption among tier-one and tier-two contractors following updated guidance from the UK BIM Framework. Firms including Mace Group and Morgan Sindall have confirmed they are mandating IFC 4.3 exports from subcontractors on public sector projects. The open standard, supported natively by Blender's BlenderBIM add-on and FreeCAD, is being positioned as a practical alternative to proprietary Autodesk formats on government frameworks.
