+
+   The *Curve Trim* node.
+
+The *Curve Trim* node makes each spline in the curve shorter by removing sections at the start and
+end of each spline.
+
+Bezier splines will still be Bezier splines in the output, with the first and last control point and
+its handles moved as necessary to keep the shape the same. NURBS splines will be transformed into poly
+splines in order to be trimmed.
+
+
+Inputs
+======
+
+Curve
+   Standard geometry input with a curve component.
+
+Start
+   The factor or length used to dertermine where to start each output spline.
+   
+End
+   The factor or length used to dertermine where to end each output spline.
+
+
+Properties
+==========
+
+Mode
+   How to find endpoint positions for the trimmed spline
+
+   :Factor:
+      Find the endpoint positions using a factor of each spline's length.
+      The input values should be between 0 or 1.
+   :Length:
+      Find the endpoint positions using a length from the start of each spline.
+      The input values should be between 0 and the length of the splines.
+
+
+Outputs
+=======
+
+Curve
+   Standard geometry output with the trimmed curve component.
