For us the coordination aspect of the job which is becoming a pre-requisite is traded as AMEP. A good question would be if it could be done easier with revit and exported and traded as AMEP. I remember reading that if the plans you get are in cad stay with cad it is too much work to design in revit off of cad backgrounds. I don't know if that is still the case.
Since AMEP is a design to fabrication program I am not sure if the information that is sent to the machinery would be lost in the translation.
I see that some things like Trimble's point creator works in both, to then be used in their layout solutions.
We are in the electrical end of it so it does not matter to us. It seams to me that the mechanical end of it is what is steering the ship.
The re-seller for us was dissapointed that they could not sell us revit. They could have if they would of let us know of the price and package change for 2013. Now there is no MEP suite and you have to get a suite that has to many things bundled together for a lot more money.Navis would have been nice but I get by with TeklaBimSight which is free. Our Re-seller said things like they hate to work in autocad because it is to much like work. It does seam like a lot of people say they won't switch back to cad but I don't know if it is all hype. I can't wait to read stykface's reply now that he made the switch. AMEP is all we need and it is a powerfull and amazing program. I would just like to learn revit incase it does take over the coordination world.
