Wire (Polyline)

In one sentence: Draws a connected sequence of straight line segments by clicking successive points; can be closed into a face.

Overview

Workbench: Draft
Menu: Draft → Drafting → Wire
Command: Draft_Wire

Creates a Draft::Wire with two or more vertices. Each click adds a segment. The wire can remain open or be closed back to the first point to form a polygon.

Step-by-step

  1. Activate Draft → Drafting → Wire.
  2. Click points one by one to add segments.
  3. Press A to toggle Relative mode (offset from previous point).
  4. Press C to close the wire back to the first point.
  5. Press Enter or double-click the last point to finish open.

Key properties

Property Description
Points List of all vertices
Closed Whether the last vertex connects to the first
Make Face Create a filled face when Closed is True
Fillet Radius Optional radius to fillet all corners
Chamfer Size Optional chamfer on all corners

Python API

import Draft

pts = [
    App.Vector(0, 0, 0),
    App.Vector(50, 0, 0),
    App.Vector(50, 50, 0),
    App.Vector(0, 50, 0),
]
wire = Draft.make_wire(pts, closed=True, face=True)
App.ActiveDocument.recompute()

Common mistakes and pitfalls

Make Face requires a coplanar closed wire

If Make Face is True but the wire is not closed or its vertices are not coplanar, FreeCAD cannot compute a face. Check the Closed property and verify all points share the same Z value.
