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

shape = createMeshView(obj, direction=FreeCAD.Vector(0, 0, -1), outeronly=False, largestonly=False)
  • Creates a flat shape that is the projection of the given mesh object (obj) in the given direction.
  • If outeronly is True only the outer contour is taken into consideration, discarding the inner holes.
  • If largestonly is True only the largest segment of the given mesh will be used.

Use to display the resulting flat shape.

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

Shape = Wall.Shape.copy(False)
Shape.Placement = Wall.getGlobalPlacement()

mesh_obj = FreeCAD.ActiveDocument.addObject("Mesh::Feature", "Mesh")
mesh_obj.Mesh = MeshPart.meshFromShape(Shape=Shape, MaxLength=520)

XAxis = FreeCAD.Vector(1, 0, 0)
YAxis = FreeCAD.Vector(0, 1, 0)
ZAxis = FreeCAD.Vector(0, 0, -1)

s1 = Arch.createMeshView(mesh_obj, ZAxis)
s2 = Arch.createMeshView(mesh_obj, XAxis)
s3 = Arch.createMeshView(mesh_obj, YAxis)
