The Draft Fillet command creates a fillet, a rounded corner, or a chamfer, a straight edge, between two selected edges. In version 0.21 and below the command only works properly if both selected edges are straight.

Several fillets and chamfers created between two edges


  1. Select two objects with one edge that meet in a single point. See Notes.
  2. There are several ways to invoke the command:
    • Press the Fillet button.
    • Select the Drafting → Fillet option from the menu.
    • Use the keyboard shortcut: F then I.
  3. Enter the Fillet radius. Note that the command will not succeed if the radius is too large for the selected edge objects.
  4. Optionally check the Delete original objects option.
  5. Optionally check the Create chamfer option.
  6. If you have selected one of the two previous options: Click in the Fillet radius input box.
  7. Press Enter.

  • A Draft Fillet cannot be edited nor is it linked to the objects that were used to create it.
  • If selected objects have multiple edges, their first edge will be used. This may not be the edge that was picked in the 3D view.
  • A Draft Wire that has at least three points can be filleted or chamfered by changing its ДанныеFillet Radius or ДанныеChamfer Size respectively. Since Draft Lines and Draft Wires, can be joined with the Draft Wire command, the Draft Join command or the Draft Upgrade command, this provides an alternative method for creating fillets and chamfers.

A Draft Fillet object is derived from a Part Part2DObject and inherits all its properties. It also has the following additional properties:



  • ДанныеEnd (VectorDistance): (read-only) specifies the end point of the fillet.
  • ДанныеFillet Radius (Length): (read-only) radius with which the fillet was created.
  • ДанныеLength (Length): (read-only) specifies the total length of the fillet.
  • ДанныеStart (VectorDistance): (read-only) specifies the start point of the fillet.



  • ВидArrow Size (Length): specifies the size of the symbol displayed at the end of the fillet.
  • ВидArrow Type (Enumeration): specifies the type of symbol displayed at the end of the fillet, which can be Dot, Circle, Arrow, Tick or Tick-2.
  • ВидEnd Arrow (Bool): specifies whether to show a symbol at the end of the fillet, so it can be used as an annotation line.
  • ВидPattern (Enumeration): not used.
  • ВидPattern Size (Float): not used.

To create a Draft Fillet use the make_fillet method of the Draft module:

fillet = make_fillet([edge1, edge2], radius=100, chamfer=False, delete=False)
  • Creates a Fillet object between edge objects edge1 and edge2, using radius for the curvature.
  • If chamfer is True it will create a straight edge instead of a rounded edge.
  • If delete is True it will delete the given edge1 and edge2, and leave only the new object.
