This brings up a good question then, What do you guys usually do for presentation work?
I switch between it, 3ds Max using this addon
http://www.west-racing.com/mf/?page_id=2979. Sometimes my presentations are completed entirely in civil 3d. The surfaces created, images draped, and render made. It's as high-def as the aerial available and usually more than enough required for discussion.
The key strength of infraworks is it's ability to import aerials / surfaces and and draw conceptually though. It lacks enormously on custom modeling (buildings, signs, unique roadways, etc). Users still have to really on a separate application (most often 3ds Max or Autocad itself). For us civil engineer nerds at a local scale that doesn't matter much. Still it was a long time coming, but I'd say compared to the products that been produced concerning visualization Autodesk should continue to be criticized until we have a visual application worthy of today's automation and presentation standards, and the thousands upon thousands of dollars they charge for it lol every year now.
I see the struggle coming where companies will shove 360 down clients throats and it will be the new norm though. To me, this means that more accurate, higher resolution, more realistic and unique content will be "better" and more likely to award a project. This includes the ability to map and model 3d objects unique to a project. There will be an impossibility for smaller firms to compete against larger firms who have architect and structural engineers on board to get larger projects because of this. They will utilize Civil 3d, Revit, Navisworks, 3ds Max and Infraworks to fight for the multi-million dollar projects.
There's an entirely different level of presentation that people tend to ignore because they are used to the same old way of getting, and trying to get contracts. The ability to export sites so clients can walk around them themselves simply like a game. Infraworks has yet to provide a solution for that. To do that currently, I export my site from infraworks into 3ds Max, make some adjustments, then push it to Stingray. I've only done this once, but it resulted in a very good contract. If agencies / clients smartin up, I believe this will become the standard of the future.
