They did a webex demo for us a couple of weeks ago, but it didn't go well. Throughout the demo, we all kept wondering why the guy demonstrating the software couldn't seem to understand our questions. Then we found out he was not a structural engineer (not even close). He was an architect, and he had no idea what kind of information we would be likely to want to show on our drawings.
They are trying to schedule another demo with their (apparently only) structural person, but his availability is pretty limited, so it might be a month or more before we can get it set up.
I did manage to garner a little information from the demo, though. It looks like the software is very powerful, and fairly flexible, but also extremely complicated. It's fairly obvious to me that it will do what we want it to do, but I think it is going to take a very long time to learn how to be productive with it. The user interface is extremely complicated, but if you could ever master it I imagine you could really crank out the work.
