Hi,

I simply found that a fitted spline by default does not allow any typical spline operation, and does not have any spline points, and cannot add any Tangency Control or Curvature control.

After "Simplify Spline", we then would be able to do the normal spline operations. And in fact before "Simplify Spline", the number of "Spline Point" as being displayed by "Simplify Spline" dialogue is zero.

Could someone explain more on why "Fit Spline" would result in this?
