Description

The Draft Fillet.svg Draft Fillet command creates a fillet, a rounded corner, or a chamfer, a straight edge, between two Draft Lines.

Draft Fillet example.png

Several fillets and chamfers created between two lines

Usage

  1. Select two Draft Lines that meet in a single point.
  2. There are several ways to invoke the command:
    • Press the Draft Fillet.svg Draft Fillet button.
    • Select the Drafting → Draft Fillet.svg Fillet option from the menu.
    • Use the keyboard shortcut: F then I.
  3. Enter the Fillet radius. If the Create chamfer option is selected this will be the size of the chamfer (the length of the straight edge). Note that the command will not succeed if the radius or the chamfer size is too large for the selected lines.
  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.

Options

  • Press Esc or the Close button to abort the command.

Notes

  • A Draft Fillet cannot be edited nor is it linked to the lines that were used to create it.
  • Only Draft Lines, that is Draft Wires with only two points, are supported at the moment.
  • A Draft Wire that has at least three points can be filleted or chamfered by changing its DataFillet Radius or DataChamfer 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.

Properties

See also: Property editor.

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

Data

Draft

  • DataEnd (VectorDistance): (read-only) specifies the end point of the fillet.
  • DataFillet Radius (Length): (read-only) radius with which the fillet was created.
  • DataLength (Length): (read-only) specifies the total length of the fillet.
  • DataStart (VectorDistance): (read-only) specifies the start point of the fillet.

View

Draft

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

Scripting

See also: Autogenerated API documentation and FreeCAD Scripting Basics.

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

fillet = make_fillet([line1, line2], radius=100, chamfer=False, delete=False)
  • Creates a Fillet object between lines line1 and line2, using radius for the curvature.
  • If chamfer is True it will create a straight edge with the length of radius, instead of a rounded edge.
  • If delete is True it will delete the given line1 and line2, and leave only the new object.

Example:

import FreeCAD as App
import Draft

doc = App.newDocument()

p1 = App.Vector(0, 0, 0)
p2 = App.Vector(1000, 1000, 0)
p3 = App.Vector(2000, 0, 0)

line1 = Draft.make_line(p1, p2)
line2 = Draft.make_line(p2, p3)

doc.recompute()

fillet = Draft.make_fillet([line1, line2], radius=500)

doc.recompute()
