Draft

Description

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.

In version 1.0 and below if the selected objects have multiple edges, their first edge will be used. This may not be the edge that was picked in the 3D view.

Several fillets and chamfers created between two edges

Usage

1. Select two edges that meet in a single point.
2. There are several ways to invoke the command:
   • Press the Fillet button.
   • Draft: Select the Drafting → Fillet option from the menu.
   • BIM: Select the 2D 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.

Options

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

Notes

• A Draft Fillet cannot be edited nor is it linked to the edges that were used to create it.
• 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([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.

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)

edge1 = Draft.make_line(p1, p2)
edge2 = Draft.make_line(p2, p3)

doc.recompute()

fillet = Draft.make_fillet([edge1, edge2], radius=500)

doc.recompute()
