Description

The Draft Fillet command creates a fillet, a rounded corner, between two Draft Lines. Alternatively, it can create a chamfer, a straight edge, between those two lines.

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 button.
    • Select the Drafting → Fillet option from the menu.
  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

  • The resulting fillet object is not editable.
  • Only single lines are supported at the moment; Draft Wires, that is, lines with multiple points, may not produce the desired result.
  • A Draft Wire that has at least three points can be fillet 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

Data

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

View

  • ViewEnd Arrow: if it is true it will display a symbol at the last point of the line, so it can be used as an annotation line.
  • ViewArrow Size: specifies the size of the symbol displayed at the end of the line.
  • ViewArrow Type: specifies the type of symbol displayed at the end of the line, which can be "Dot", "Circle", "Arrow", "Tick", or "Tick-2".

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()
