The Facebinder tool creates a surface object from the selected faces of a solid object. It is parametric, meaning that if you modify the original object, the Facebinder updates accordingly. If you move and rotate the Facebinder, it will stay linked to the original faces.

It can be used to create an extrusion from a collection of faces from other objects. A typical use is in architectural design to build an object that covers several walls, for example, a wall paper, or wall finish.

Facebinder created from the faces of solid walls

How to use

  1. Pick one face, or hold Ctrl and pick several faces, from solid objects.
  2. Press the Draft Facebinder.png Facebinder button, or press F then F keys.

The Facebinder can be edited by double clicking on the element in the tree view. Then you can change the faces that are part of the object.

  • To add a face, click on a face of a solid object in the 3D view, and then click on the Arch Add.svg Add button.
  • To remove a face, select one of the sub-elements in the list, and then click on the Arch Remove.svg Remove button.
  • Press Esc or the OK button to complete the edition.


This object has no options when it's being created. Only selected faces will be used to create the Facebinder object.



  • DataExtrusion: specifies an extrusion thickness to apply to all faces of the shape.
  • DataRemove Splitter: if it is true it tries to fuse the internal intersections of the Facebinder when it extruded.
  • DataSew: if it is true it tries to perform a topological sewing operation on the Facebinder when it extruded.


  • ViewPattern: specifies a Draft Pattern with which to fill the face of the shape. This property only works if ViewDisplay Mode is "Flat Lines".
  • ViewPattern Size: specifies the size of the Draft Pattern.

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

Facebinder = makeFacebinder(selectionset)
  • Creates a Facebinder object from the given selectionset, which is a list of SelectionObjects as returned by FreeCADGui.Selection.getSelectionEx(). Only selected faces are taken into account.
    • selectionset can also be a PropertyLinkSubList.

A PropertyLinkSubList is a list of tuples; each tuple contains as first element an object, and as second element a list (or tuple) of strings; these strings indicate the names of the sub-elements (faces) of that object.

PropertyLinkSubList = [tuple1, tuple2, tuple3, ...]
PropertyLinkSubList = [(object1, list1), (object2, list2), (object3, list3), ...]
PropertyLinkSubList = [(object1, ['Face1', 'Face4', 'Face6']), ...]
PropertyLinkSubList = [(object1, ('Face1', 'Face4', 'Face6')), ...]

The thickness of the Facebinder can be added by overwriting its Extrusion attribute; the value is entered in millimeters.

The placement of the Facebinder can be changed by overwriting its Placement attribute, or by individually overwriting its Placement.Base and Placement.Rotation attributes.
