I have a workspace that has multiple line segments and several overlapping polygons, I would like to clip the line segments to the polygons without gaining or losing line segments in the polygon, I have tried cloning and also geometry replacement and spatial relator but I always end up with merged line segments inside the polygons after clipping. Some of the resulting lines that are clipped span the entire length of the polygon.

 

Here is what I am currently attempting, I am using method from this answer in the forum. I have the parameters set the same as in the post made by takashi

I would use a spatial relator to build a list on each line of the polygons it intersects. Explode the list, then use the polygon id as a group by in a clipper
