is here anybody doing full BIM with IFC import-export?

hi,

i intend to implement the full BIM with a virtual 3d model and IFC input/output from MEP, HVAC and/or structural branches in my new project (a restoration of an old industrial edifice in central europe into a company hq, some 1,000 msq.).

i will do as much BIM as it's possible, but i don't have much practice in that field.

i'd like to know if there is anybody with such an experience to mutually exchange bits of working knowledge?

thanks in advance,

rob

chris,

thanks for your input.

my potential investor doesn't know much about BIM, so he doesn't care about the software which will eventually be vw (i have to implement the v2010, as the building is an old one with varying wall thickness) which i own.

currently i study the ifc import and export manuals, and it should be ok from my part (architecture), but my biggest concern is the possible incompatibility during the branches ifc exchanges (hvac & mep).

as for the structural it won't be much of slabs restoration, so i could even convert the structual engineer's supporting profiles into 3d model by myself manually.

thanks again,

rob

You're going to have a lot of problems using IFC to communicate between Vw2008 and Revit (which version, it matters). The quality of the the 2008 IFC export is not very good compared to 2010. Vw2009 SP4 was a BIG step up and 2010 was another big one, as well.

You can try using DWG/DXF, as the AutoCAD users have to, but these results will also be mixed as Revit's pre-2010 DWG/DXF support isn't perfect either.

Right now the best known/tested performance using IFC to communicate with Autodesk products is between Vw2010 and AutoCAD Architecture/MEP/Structural Detailing 2010 and/or Navisworks 2010. Revit 2010 is in third place, but definitely better than their 2009 or earlier versions, which are almost completely unreliable.

Sorry, that's the current state of things. Much quality development on IFC has lagged as our competitors have slowly taken up the pace to improve their support, also.
