Description

The Arch CutPlane tool cuts a solid Arch object like an Arch Wall or Arch Structure with a planar face.

Left: Before applying the CutPlane tool. Middle: resulting wall after the cut is done. Right: yet another optional result

Usage

If the cutting plane is to be derived from a straight edge (introduced in version 1.0) optionally align the working plane:
- The selected edge cannot be parallel to the normal of the working plane.
- The generated cutting face will be perpendicular to the working plane.
Select the object to be cut.
Do one of the following:
- Select an object with a single planar face. introduced in version 1.0
- Select a planar face in the 3D view.
- Select an object with a single straight edge. introduced in version 1.0
- Select a straight edge in the 3D view. introduced in version 1.0
There are several ways to invoke the command:
- Press the Cut with plane button.
- Select the Modify → Cut with plane option from the menu.
Choose Behind or Front to indicate on which side of the cutting face material should be removed.
Press the OK button.

Scripting

See also: Arch API and FreeCAD Scripting Basics.

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

cutObj = cutComponentwithPlane(archObject, cutPlane, sideFace)

Creates a cutObj object from the given archObject, which is cut by cutPlane, which is the face of another object.
- archObject should be a SelectionObject obtained from FreeCADGui.Selection.SelectionEx()[0].
- cutPlane should be a FaceObject obtained from FreeCADGui.Selection.SelectionEx()[0].SubObjects[0].
sideFace specifies on which side of the FaceObject a volume will be created; this volume will then be used to subtract from the archObject. If sideFace is 0 it will create a volume in the rear of the face, otherwise it create it in front of the face.

Example:

import FreeCAD, FreeCADGui, Draft, Arch

p1 = FreeCAD.Vector(0, 0, 0)
p2 = FreeCAD.Vector(2000, 2000, 0)

Line = Draft.makeWire([p1, p2])
Wall = Arch.makeWall(Line, width=150, height=2000)

p3 = FreeCAD.Vector(0, 2000, 0)
p4 = FreeCAD.Vector(3000, 0, 0)

Line2 = Draft.makeWire([p3, p4])
Wall2 = Arch.makeWall(Line2, width=150, height=2000)
FreeCAD.ActiveDocument.recompute()

# Select the Wall
main_object = FreeCADGui.Selection.getSelectionEx()[0]

# Select the face of Wall2
selection = FreeCADGui.Selection.getSelectionEx()[0]
cut_face = selection.SubObjects[0]

cutObj = Arch.cutComponentwithPlane(main_object, cut_face, 0)
FreeCAD.ActiveDocument.recompute()

Wall3 = Draft.move(Wall, FreeCAD.Vector(-4000, 0, 0), copy=True)
Wall4 = Draft.move(Wall2, FreeCAD.Vector(-4000, 0, 0), copy=True)
FreeCAD.ActiveDocument.recompute()

# Select the Wall3
main_object2 = FreeCADGui.Selection.getSelectionEx()[0]

# Select the face of Wall4
selection2 = FreeCADGui.Selection.getSelectionEx()[0]
cut_face2 = selection2.SubObjects[0]

cutObj2 = Arch.cutComponentwithPlane(main_object2, cut_face2, 1)
FreeCAD.ActiveDocument.recompute()
