Controls the tension for an interpolation spline created using the Minimum Energy fit method. When you apply tension to interpolation splines created with other fit methods, they automatically convert to Minimum Energy splines, and change shape.
Right-click an interpolation spline to see the context menu options.
Sets the tension for the spline. The default position is zero. A value closer to 1 sets loose tension. A value closer to 100 tightens the spline between the fit points.
As you move the slider position, a preview graphic updates dynamically.
