on the job i am currently running all more foreman use a Ipad with bluebeam revu. I setup layers to use installation of ductwork and currently this isnt supported on the ipad. This in my opinion would be a vital tool for field use to allow turning individual layers off. This is currently only available on the laptop version and doesn't help my field guys since they cant isolate certain layers. I feel this is something worth investing in to give your clients (us) valuable tools to perform better.
