This is so cool.
Using Solid Elements Operations and this object, you can cleanly slope the top of a curving wall. Handy for landscaping.
The length becomes the inside radius of the trimmer. Give a width a bit wider than the wall, and make the radius a little smaller than the wall's inside radius.
The thickness can generally be left alone. It just has to be >0. Of course if you want to leave the object showing for a flagstone cap, go ahead.
The arc angle is graphically editable by the outside top node. The inside nodes all edit the radius. The outside middle node edits the width.
Make the object the material you want for the top of the wall. SEO doesn't seem to always get this right.
