Draft SelectPlane


This command will place a Plane Proxy object aligned to the current Working Plane.

This proxy object can be used like a face to quickly change the working plane using the Draft SelectPlane tool. The camera position and visibility of the objects in the 3D view can be saved in the proxy object, and restored at anytime when the Draft SelectPlane tool is used.

  1. Make sure the Working Plane is set as you want.
  2. Then go to the menu Draft → Utilities → Draft SetWorkingPlaneProxy.png Create Working Plane Proxy.


  • The working plane stored in the Proxy object can be restored by double-clicking the object in the tree view, or by selecting the Proxy object and using the Draft SelectPlane.svg Draft SelectPlane button.
  • The position of the camera is stored in the Proxy object upon creation. This position can be updated anytime: zoom, pan and rotate the view as you wish, then right-click the Proxy object in the tree view, and select Draft SelectPlane.svg Write camera position.
  • The visibility state of all objects is also stored in the Proxy object upon creation. This state can be updated anytime: set the ViewVisibility property of the objects to true or false as desired, then right-click the Proxy object in the tree view, and select Draft SelectPlane.svg Write objects state.
  • Plane proxies can be moved and rotated like any other object so that they define the desired working plane. Their visual appearance can also be changed in the Éditeur de propriétés.



  • DataPlacement: specifies the position of the proxy object and the corresponding working plane.
    • DataPosition: specifies the coordinates of the proxy object.
    • DataAngle: specifies the rotation angle of the proxy object.
    • DataAxis: specifies the axis to use for the rotation angle.


  • ViewDisplay Size: specifies both length and width of the proxy object. If the object is created in the tree view but no element is visible in the 3D view, increase this value until it is visible.
  • ViewArrow Size: specifies the size of the arrows indicating the three axes of the plane proxy.
  • ViewRestore View: if it is true the camera position will be restored to the saved position when using the proxy with Draft SelectPlane.svg Draft SelectPlane or by double-clicking on it.
  • ViewRestore State: if it is true the visibility state of all objects will be restored to the saved state when using the proxy with Draft SelectPlane.svg Draft SelectPlane or by double-clicking on it.

Working plane proxy objects can be used in macros and from the Python console by using the following function:

WPProxy = makeWorkingPlaneProxy(placement)
  • Creates a WPProxy object from the given placement which is a FreeCAD.Placement.
    • A placement is defined by a base point, given by its FreeCAD.Vector, and a FreeCAD.Rotation.

The size of the Plane Proxy can be changed by overwriting its ViewObject.DisplaySize and ViewObject.ArrowSize attributes, with units in millimeters.

The Plane Proxy has a "Face" object as its Shape attribute. This face can be used to set the current working plane by calling its alignToFace() method.


import FreeCAD, FreeCADGui, Draft

currentWP = FreeCAD.DraftWorkingPlane
place = currentWP.getPlacement()

WPProxy = Draft.makeWorkingPlaneProxy(place)
WPProxy.ViewObject.DisplaySize = 3000
WPProxy.ViewObject.ArrowSize = 200

YAxis = FreeCAD.Vector(0, 1, 0)
point2 = FreeCAD.Vector(3000, 0, 0)
place2 = FreeCAD.Placement(point2, FreeCAD.Rotation(YAxis, 90))

WPProxy2 = Draft.makeWorkingPlaneProxy(place2)
WPProxy2.ViewObject.DisplaySize = 3000
WPProxy2.ViewObject.ArrowSize = 200

Axis = FreeCAD.Vector(1, 1, 1)
point3 = FreeCAD.Vector(-3000, 3000, 0)
place3 = FreeCAD.Placement(point3, FreeCAD.Rotation(Axis, 90))

WPProxy3 = Draft.makeWorkingPlaneProxy(place3)
WPProxy3.ViewObject.DisplaySize = 3000
WPProxy3.ViewObject.ArrowSize = 200
