Need an iLogic rule to recognize a projected-curve edge in a dwg

[Anonymous]

Hello all:

Someone at this forum was very nice recently and wrote me some iLogic code to move feature-specific linework in an INV dwg to a specified layer.  It works great for most things, but I keep finding ways to break it 😞

I've discovered that it does not function correctly if the geometry on the dwg came from the projected edge of a cylinder. I've attached several files that should explain what is going on and what I need.  All the lines in the dwg should be red; the black lines are projected-curve edges.

I'm guessing that the coding "oFace" is looking throughout the model for a flat, 2d, planar face; that doesn't apply to the rounded edge of a cylinder.  

Is there another variable that will capture the lines made from the cylinder?  Thanks in advance for any help!
