I am not very familiar with Bluebeam Revu, but isn't the product that does redlining and review in PDF and lets you link it back to the BIM application?
Archicad even has a Bluebeam connection:
Hi!, yeah, that is the one. actually this i idea came because the other day i saw a video about bluebeam and found it overly complicated (maybe i saw the wrong video), with a lot of importing and exporting stuff and what not. Meanwhile i think the markup tool can streamline the revision process A LOT, at least in house, specially with this single file i propose.
But Maybe if working with many consultants the Bluebeam serves better, so ill keep reading about it.
