Description

The Draft Offset command offsets each segment of a selected object over a given distance, or creates an offset copy of the selected object.

Offsetting a Draft Wire

Usage

See also: Draft Snap and Draft Constrain.

  1. Optionally select one object. The object must lie on the current Draft working plane.
  2. There are several ways to invoke the command:
    • Press the Offset button.
    • Draft: Select the Modification → Offset option from the menu.
    • BIM: Select the Modify → Offset option from the menu.
    • Use the keyboard shortcut: O then S.
  3. If you have not yet selected an object: select an object in the 3D View.
  4. The Offset task panel opens. See Options for more information.
  5. To define the offset distance do one of the following:
    • Pick a point in the 3D View.
    • Enter a numerical value:
      1. Make sure the pointer is on the correct side of the object in the 3D View.
      2. Do not move the pointer out of the 3D View.
      3. Enter a Distance.
      4. Press Enter to finish the command.

Options

The single character keyboard shortcuts available in the task panel can be changed. See Draft Preferences. The shortcuts mentioned here are the default shortcuts.

Notes

Scripting

See also: Autogenerated API documentation and FreeCAD Scripting Basics.

To offset objects use the offset method of the Draft module. The method can only handle Draft Wires, Draft Circles, Draft Rectangles, Draft Polygons and Draft BSplines. 

offset_obj = offset(obj, delta, copy=False, bind=False, sym=False, occ=False)

Example: 

import FreeCAD as App
import Draft

doc = App.newDocument()

p1 = App.Vector(0, 0, 0)
p2 = App.Vector(1500, 2000, 0)
p3 = App.Vector(4000, 0, 0)

wire = Draft.make_wire([p1, p2, p3])
doc.recompute()

vector = App.Vector(-200, 150, 0)
offset1 = Draft.offset(wire, vector, copy=True, bind=True, sym=True)
offset2 = Draft.offset(wire, 3*vector, copy=True)
offset3 = Draft.offset(wire, 6*vector, copy=True)
offset4 = Draft.offset(wire, 9*vector, copy=True)
offset5 = Draft.offset(wire, 1.5*vector, copy=True, occ=True)

doc.recompute()
