The Arch Workbench provides a modern Building Information Modelling (BIM) workflow to FreeCAD, with support for features like fully parametric architectural entities such as walls, beams, roofs, windows, stairs, pipes, and furniture. It supports Industry Foundation Classes (IFC) files, and production of 2D floor plans in combination with the TechDraw Workbench.

The developers of Draft, Arch, and BIM also collaborate with the greater OSArch community, with the ultimate goal of improving building design by using entirely free software.
