The Tangent Threshold will smooth the connection between the arc circuits that are below the specified Angle Degree in the Tangent Threshold field to provide a smoother cutting transition between the arcs.
The more tangent the connection between arcs, the smoother the cut.
Any arc sets the maximum degree limit between the Arc Circuits, making the Circuit connections below that degree limit to be Tangent with the Tangent Tool or the Tangify All Circuits function.
This will create a seamless transition between arcs for smoother cuts.
Arc connections above the specified Angle Degree in the Tangent Threshold field will may cause the head Head to pick up and replunge when cutting.
