The Arch Building is a special type of FreeCAD group object particularly suited for representing a whole building unit. They are mostly used to organize your model, by containing floor objects.


  1. Optionally, select one or more objects to be included in your new building.
  2. Press the Arch Building.svg Arch Building button, or press the B then U keys.


  • Starting from FreeCAD version 0.18, the Building object is actually a BuildingPart with its DANEIFC Type property set to "Building". You can convert any BuildingPart to a Building simply by changing its IFC Type.
  • After creating a building, you can add more objects to it by drag and dropping them in the Tree View or by using the Arch Add.svg Arch Add tool.
  • You can remove objects from a building by drag and dropping them out of it the Tree View or by using the Arch Remove.svg Arch Remove tool.


  • DANEBuilding Type: The type of this building, to choose from a list

The Building tool can be used in macros and from the Python console by using the following function:

Building = makeBuilding(objectslist=None, baseobj=None, name="Building")
  • Creates a Building object from objectslist, which is a list of objects, or baseobj, which is a Shape.


import FreeCAD, Draft, Arch

p1 = FreeCAD.Vector(0, 0, 0)
p2 = FreeCAD.Vector(2000, 0, 0)
baseline = Draft.makeLine(p1, p2)
baseline2 = Draft.makeLine(p1, -1*p2)

Wall1 = Arch.makeWall(baseline, length=None, width=150, height=2000)
Wall2 = Arch.makeWall(baseline2, length=None, width=150, height=1800)

Building = Arch.makeBuilding([Wall1, Wall2])

Site = Arch.makeSite(Building)
