I need to beam complex P&IDs for client viewing. The drawings are in AutoCAD2012. I find it difficult to zoom and pan to the desired place. Beaming individual component P&IDs is also not an option as the client usually wants to see the enitre layout first. The entire layout, when beamed is unreadable without zooming. I was hoping for a solution similar to drilling down in databases (clubbing of data when we at the top levels and then the ability to view details when clicking on a particular cell); where only the important lines and symbols are shown at the top levels so that they can clearly be seen on beaming. Thanks a lot for your help
