I'm trying to create a pavement around my building. But the slicing of the geometry does not work out properly when it comes to sharp turns. The meshes tends to intersect, overlap and deform rather then being sliced. I've tried the same thing with your presets for pavements in RailClone, and they have similar problems.
See the attached images for examples. In my own example I've designed the pavement with a seperate RC object using the Array 2S.
