This is corrected in Claris CAD 2.0v3
Q. I have copied a spline to the clipboard and when I look at the clipboard it looks incorrect. Why is this.
A. Claris CAD shows two versions of the Spline on the clipboard. The smoothed and the unsmoothed versions. There is no problem when you paste this object from the clipboard. (I.E. If the spline is supposed to be smoothed then it will be smoothed when copied from the clipboard.
