    roombounding elements in a IFC file


    Hello Reviter,

    I have to place MEP-rooms. For that, I use IFC import file. the wall are all roombounding. The link itself too.
    But it doesn`t work? I am glad about to have any help for this topic.

    Can you provide a sample of your file for troubleshooting?

      IFC from Archicad

      The IFC file is generatet by archicad. I would like to avoid draw <room separation lines> wall by wall! How can I "attach" an atribute to make the walls roombounding?

        ... the next problem is: I can´t catch any point of the modell(IFC), I can´t unterstand way?
        Even when i bind the model in the .rvt.
        I can catch opjects but no points or sections?
        I have a lot of attriputs, but the gometrie is as refernce uselese
        Can I change this ?

        BR

          Export ifc to DWG, link DWG? (long shot.. Not tested..)

            Good lord, why do you always suggest crap like that? Youre going to end up destroying someones project, eventually. We get it, you love all things AutoCAD. Doesnt mean its the answer all the time.

            Andreas2: There are a few peculiarities in Revit, about Room Bounding:

            1. Check the Associated LEVEL of the VIEW you are in. Thats the LEVEL Revit is trying to put the rooms at. So if the archicad model is room bounding, but its "a few feet higher" than the Level, it might not be working.

            2. Select the LEVEL ITSELF, and go to its properties. See what ELEVATION the ROOM COMPUTATION HEIGHT is set to. Thats the elevation off the level it is looking for room boundaries at. Does the archicad model that is set to room bounding cross that elevation?

            Let me know if that helps...

              Just going to say that "snapping" and "link DWG" should never, EVER, be in the same sentence, unless the word "never" is involved, and all caps. It's just not worth the (false) impression of a time savings.

                What I would also look for is small gaps between walls. The Wall elements Revit generates from the IFC link can be very different from the native Revit system Wall Families. Revit can use those system familes to understand that a Wall has a direction, and use that direction to bridge small gaps in Room Boundaries.
                I'm not sure if Spaces have this same problem though, you might want to try those as well.
                There must be a better way...

                  Well, i still use Revit for doing civil stuff sometimes. IFC is a someting than can be turned into many fileformats. Sometimes it helps to try something else. Importing IFC and exporting it to 3D DWG in Revit still gives much better results than the ifcimporter in AutoCAD (C3D). CIvil3d, that piec of software really redefines crap when it comes to ifc ;-) YOu may call it this geometry gym crazy, i prefer to call it "thinking out of the box"..

                    Its not thinking out of the box, its something people have tested, experimented with, documented REAL PROBLEMS with it, and its a crappy method. Bringing CAD files in to Revit causes problems in the Revit files, ESPECIALLY if you "snap" to the CAD files. Full Stop. Period. End of story.

                    Knock yourself out, if you like those kinds of problems. For other people happening across this thread: You WILL have problems in Revit if you do it.
