I am trying to create sideways of varying archs and widths to create our landscape design. It seems I cannot create a connect poly shape to a solid surface (don't even see that as an option once a poly is drawn) and the sidewalk tools create fairly rigid shapes and when they are connected changing the width does the whole length. It is a paver walkway with a few half circles, connection points, etc. Tried a slab as well but that doesn't follow terrain elevation What is the best/easiest way to create this? Thanks in advance, drawing attached. I'm using home designer architectural 2016. Image attached.
