Discretize

In one sentence: Samples an edge or wire into an ordered array of points, with five sampling modes from fixed count to adaptive deflection.

Third-party addon — installation required

The Curves workbench is not included in FreeCAD. Install it via Tools → Addon Manager → search "Curves" → Install and restart FreeCAD.

Overview

Workbench: Curves
Menu: Curves → Discretize
Command: Discretize

The result is a Points::Feature object — an ordered array of 3-D points along the edge.

Sampling modes

Mode Description
Number of points Fixed count, evenly distributed by parameter
Distance Points separated by a specified arc-length distance
Deflection Adaptive — more points where curvature is higher
Angular deflection Points placed so the chord angle stays below a threshold
Curve length Points separated by a specified chord length

Step-by-step

  1. Select an edge in the 3-D view.
  2. Choose Curves → Discretize.
  3. Select the sampling mode and parameters in the task panel.
  4. Click OK.
