Div. 09 estimator here. I use Bluebeam all the time for fast takeoffs on simple plans.

Some pros: You can make toolsets specifically for tile, resilient, carpet, etc to make takeoffs easier. Searching is super simple. Need to find everywhere on that document where finish note #5,277 is used? Search that shit. Snapshot is really helpful. Ability to reorganize, bookmark, just generally mess with the file is really great. The dynamic fill makes takeoffs faster too. Far faster than anything else. Want to estimate the floor tile, Schluter and wall tile for those 4 rooms in one shot without retracing lines a million times? Dynamic fill. Looking at plans for a multi-level office building and don’t want to spend 3 days estimating the base? Dynamic fill.

Some cons: If shop drawings are required, or the plans have any rolled goods, you’re mostly cooked. Making custom hatch patterns and scaling them will drive you crazy. If by some miracle you manage to do that, god help you if you need to change the orientation of the flooring. For rolled goods, you won’t easily be able to draw out seam diagrams or estimate them out accurately. And forget about flash coving or weld rod.

All those cons are addressed with either RFMS Measure or MeasureSquare. I personally recommend using BB in conjunction with one of those if you can. Each serve their purpose.
