FreeCAD, a Free and Open-Source (FOSS) 3D CAD modeling platform, offers BIM tools since many years with the Arch workbench. Starting from version 1.0, released in November 2024, the Arch tools have been extended and renamed to become the BIM workbench, and extended with a new native IFC system. This tutorial will walk you through the different concepts used in native IFC, and how to apply them working on an example model.
