I am currently going to start working on a arch. project on an existing commercial space. We are renovating the whole space to prepare for a new restaurant and bar. Upon til this point I have just used Revit for rendering and presentation purposes. With this fresh start of a project I wanted to look into using revit for creating construction documents by using phasing with Revit 2009. I heard that phasing can kind of be complicated at first until you get used to it and I'm totally sure how to even get started with it. So if anyone can navigate me to a website or guide of some sort for learning phasing it would be much appreciated. Thanks for your time.
