Problem with follow me

test follow me.skp (50.0 KB)
With Skatchup 2017, I am not able to use follow me with a curved shape: on the example attached, I can extrude a triangular shape along de circle base, but not the shape where a quarter circle replaces the hypothenuse of the triangle??? Can you help?

Your geometry is too small.
