Add an Equal Radius Constraint

  1. Select Sketch | Constraints | Add equal radius constraint.
  2. Select the first circle or arc. This circle or arc will keep its position.
  3. Select the second circle or arc. This circle or arc will move so that its radius is equal to the radius of the first circle or arc.
  4. Add more equal radius constraints by repeating steps 2 and 3 or finish adding equal radius constraints by pressing the ESC key or the middle mouse button.
You can also dimension several circles or arcs at the same time:
  • Select several circles or arcs.
  • Select the context-sensitive function Constraints > Radius.
  • A radius constraint is added to the circle or arc that was selected first and an equal radius constraint is added to the rest of the circles or arcs.
