Hello, so I am working on a project for my site engineering class and on the site he is requiring us to place a fairly large building which he has instructed us to create positive drainage on all sides of the building to eventually run into a bioswale that we are required to include starting at the high point of the house. I can't figure out how to create a pad in the site modifer tools that achieve this effect. I was wondering if there is any workflows or workarounds that will help achieve what I am going for
