The underside of the walkways don't always aesthetically align due to the design. The walkways currently have 2 beams going one way and 1 beam going another on the underside. This design choice does not allow for uninterrupted flow of walkway connections. Example: I place 2 corners next to each other to create a 180 degree turn and the bottom beams no longer line up which breaks the aesthetic.
My suggestion: make the underside have either 1 beam both directions or 2 beams both directions. I think 1 beam both directions would be best as it might be less geometry and also then a central beam could be added to the underside of the ramps for a complete tie in.
