Trim a Spline Curve or Remove a Part from It

Trim an open spline curve or remove a part from it by using other lines. However, other lines can not be trimmed with a spline curve. Trimming creates the control points and Tangent handles in the curve's ends automatcally. The function also changes the effect area of the tangent handles, so that the curve's shape stays as original as possible.

Trim a spline curve with the function Trim line to another line.
Remove a part from a spline curve with the function Delete Section.

Note:

If the spline curve uses fixed parametrization, the parametric values are not edited. The parametrization of a curve does not correspond the dynamic parametrization after the trim function. Changing to dynamic and back to fixed parametrization after the trimming changes the shape of the curve.
The closed spline line cannot be cut in order to create an open spline line.
