The Equal radius command constrains the radius of a 2D circle or arc made with Draft Workbench tools in relation with a workplane.

It links the radius of the 2D circle or arc with the radius of another 2D circle or arc.

The radius value of the first selected circle or arc equals the radius value of the second circle or arc.


  1. Select a 2D circle or arc to constrain.
  2. Select another 2D circle or arc to read its radius value.
  3. Activate the Equal radius command using the:
  4. Press the Solve constraints or the Quick solve button to recompute
(if Auto recompute and Smart recompute are disabled).
