    IFC Export

    Hi All,

    I'm having a bit of trouble with an export to IFC. After I make the IFC file and link it into a fresh file to check it, there are a number of objects that have shifted down. i've checked these items and they are set to the correct level and offset slightly as would normally be the case.
    Its almost like floor objects with a node displacement creates this shift. but not all of them.... Any ideas? I'm currently looking through the translator options but this is rather new to me so any help would be much appreciated.

    have you checked the IFC itself (before linking back in to check it)?
    Try the solibri model viewer. If wrong there you know its an export problem

      Just tested this. Model is the same when opened in solibri Model Viewer so it is the export process that is doing it. There are other objects that are on the same level, and have subelements modified too. nothing else that i can distinguish as different for these particular floors.

      We're using revit 2016 and cannot upgrade at this time too.

        What version of Revit are you using? Are you using Autodesk's Alternate UI version?

          You might want to post your question here...

          https://sourceforge.net/p/ifcexporte...ssion/general/

          It's a more IFC/Revit specific forum.

          Also, when you exported, did you use the open source IFC exporter? https://sourceforge.net/projects/ifcexporter/

            (just a headsup - I believe thats the same one as the Autodesk Alternate UI as mentioned in my post above)

              using Autodesks Alternate UI 16.2.0.0 . IFC 2x3 Coordination View.. needing to read a bit more into it to know where you choose your exporter.

                If its loaded then just using the export to IFC will use the alternate UI.(You can tell because the UI header says its the alternate)UI.png

                  I haven't encountered some elements being at the wrong elevation in the same file. I have however encounterred whole files having incorrect elevations. This is addressed in the Alternate UI, and may fix your problem also.
                  1. Click Modify Setup.
                  2. Select the 'Advanced' Tab.
                  3. Check the 'Include IFCSITE elevation in the site local placement origin' checkbox.
                  4. Export.

                  Let us know if this has any impact.
