I have a simple piece of 2D geometry in the blue-red plane. I want to turn it into a ring, by using follow-me around a circle in the red-green plane (or a plane parallel to the red-green plane. I select the circle, switch to follow-me, then click on my 2D geometry. Ketchup produces a ring, but it’s missing pieces corresponding to some of the curves that comprise the geometry.

Intuition suggests that there is an extra step I’m missing, that would bind together the curves of my geometry, which were drawn separately although I was scrupulous to make sure that all the curves met at endpoints and formed an unbroken figure in a single plane.

Any ideas? I’m attaching the file, plus 2D images of the geometry and the ring that Sketchup creates. Thanks,
