Description

The Part Chamfer command chamfers the selected edge(s) of an object. A dialog allows you to choose which edges to work on as well as modify various chamfer parameters.

Plate with chamfered corners

Usage

  1. Optionally select one or more edges in the 3D View.
  2. There are several ways to invoke the command:
    • Press the Chamfer button.
    • Select the Part → Chamfer option from the menu.
  3. The Chamfer Edges task panel opens.
    • Optionally (re-) select an item in the Selected shape list in the Shape section or in the 3D View.
    • Edit the chamfer parameters.
  4. Press OK to close the task panel and apply the chamfer.

Options

Dialog-chamfer

Properties

Base

Limitations

Chamfer might do nothing if the result would touch or cross the next adjacent edge. So if you do not get the expected result, try with a smaller value. This is the same for Part Fillet.

Scripting

The Chamfer command can by used in macros and from the Python Console by adding a Chamfer object to the document.

Example Script: 

import Part
cube = FreeCAD.ActiveDocument.addObject("Part::Feature", "myCube")
cube.Shape = Part.makeBox(5, 5, 5)
chmfr = FreeCAD.ActiveDocument.addObject("Part::Chamfer", "myChamfer")
chmfr.Base = FreeCAD.ActiveDocument.myCube
myEdges = []
myEdges.append((1, 1.5, 1.25)) # (edge number, chamfer start length, chamfer end length)
myEdges.append((2, 1.5, 1.25))
myEdges.append((3, 1.5, 1.25))
myEdges.append((4, 1.5, 1.25))
myEdges.append((5, 1.5, 1.25))
myEdges.append((6, 1.5, 1.25))
myEdges.append((7, 1.5, 1.25))
myEdges.append((8, 1.5, 1.25))
myEdges.append((9, 1.5, 1.25))
myEdges.append((10, 1.5, 1.25))
myEdges.append((11, 1.5, 1.25))
myEdges.append((12, 1.5, 1.25))
chmfr.Edges = myEdges
FreeCADGui.ActiveDocument.myCube.Visibility = False
FreeCAD.ActiveDocument.recompute()

Example Script Explanation: 

import Part
cube = FreeCAD.ActiveDocument.addObject("Part::Feature", "myCube")
cube.Shape = Part.makeBox(5, 5, 5)

chmfr = FreeCAD.ActiveDocument.addObject("Part::Chamfer", "myChamfer")

chmfr.Base = FreeCAD.ActiveDocument.myCube

myEdges = []
myEdges.append((1, 1.5, 1.25)) # (edge number, chamfer start length, chamfer end length)
myEdges.append((2, 1.5, 1.25))
myEdges.append((3, 1.5, 1.25))
myEdges.append((4, 1.5, 1.25))
myEdges.append((5, 1.5, 1.25))
myEdges.append((6, 1.5, 1.25))
myEdges.append((7, 1.5, 1.25))
myEdges.append((8, 1.5, 1.25))
myEdges.append((9, 1.5, 1.25))
myEdges.append((10, 1.5, 1.25))
myEdges.append((11, 1.5, 1.25))
myEdges.append((12, 1.5, 1.25))

chmfr.Edges = myEdges

FreeCADGui.ActiveDocument.myCube.Visibility = False

FreeCAD.ActiveDocument.recompute()
