The Remove tools allows you to do 2 kinds of operations:

  • Remove a subcomponent from an Arch object, for example remove a box that has been added to a wall, like in the Arch Add example
  • Subtract a shape-based object from an Arch component such as a wall or structure

The counterpart of this tool is the Arch Add tool.

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

removeComponents(objectsList, host=None)
  • Removes the given objects in objectsList from their parents.
  • If a host object is specified, this function will try adding the objects in objectsList as holes to the host.


import FreeCAD, Draft, Arch

Line = Draft.makeWire([FreeCAD.Vector(0, 0, 0),FreeCAD.Vector(2000, 2000, 0)])
Wall = Arch.makeWall(Line, width=150, height=3000)

Box = FreeCAD.ActiveDocument.addObject("Part::Box", "Box")
Box.Length = 900
Box.Width = 450
Box.Height = 2000

Draft.rotate(Box, 45)
Draft.move(Box, FreeCAD.Vector(1000, 700, 0))

Arch.removeComponents(Box, Wall)
