Hi everyone, So I'm creating a project for school on a sloped site, where I'm using curved walls as paths by making them very wide and shallow. What I'd like to do next is use the bottom of these wall path things as pads but a wall Is not a compatible object to do to. I can create pads from polygons at key points to sort of get to where I need to be, but is there a more elegant solution? Thanks
