Hey guys I am in the process of getting a 16x32 rectangular Vinyl liner pool installed and I am trying to find good free software(or very inexpensive) to help design my backyard. We have a 12x16 concrete slab off our patio door that we currently have a pergola and a table and chairs. We intend to connect the pool concrete border with this concrete slab (there is about 5 feet in between) using poured concrete (pool builder charges $8 a square foot). I wanted to lay things out on something other than a piece of paper. Does anyone know of any software I can use ?
