Concentric Constraint

Available in TurboCAD LTE Pro / DoubleCAD Pro only


Makes two arcs/circles concentric - sharing the same center point. You can also use this tool to place a point or endpoint at the center of a circle or arc.

  1. Start with two arcs/circles. Activate the Concentric constraint and select the arc/circle you want to make concentric. This object will move to the second.
  2. Select the second arc/circle. . . . and the circle/arc moves so that its center meets the endpoint or point.
