Hi Matadem, one other method is to generate a pattern of line segments using Transform > Array > Dir, and then map them onto a curve using Transform > Deform > Flow as described here:

To use _PatternSelection you would first need to split up the curve into pieces. You split up a curve into pieces by drawing a point object (Draw curve > More > Point) at the start of the curve, then select it and use Transform > Array > Curve to duplicate the point along the curve, then select the curve and run Edit > Trim and use the points as the cutting objects.

Then after you have the curve split up that's when you could use _PatternSelection . Before running it select all the pieces and then _PatternSelection can narrow the selection down by deselecting every other piece.
