I like that it has many options to create different layouts with various sizes/quantities as well in addition there are some limitations such water flow rate which limits how much we can design but otherwise everything seemed great! Also i have nothing bad about using this software because its good so far no problems or anything dislike yet only thing was when you first open up your file after uploading sometimes takes time before showing results however other than those minor issues all seems fine :) Great product if u want an efficient tool without having high costs also makes us more productive since our jobs become easier now by knowing where things need fixing etc.
