Hi,
Upon importing an IFC model into Revit i have encountered a problem. Members which were previously shown in the BIMViewer do not show up in the Revit, does anyone have any suggestions as to why this may be, and any fix's which are available? Attached is the error log i am greeted with upon loading of the model.
Hello BillyNoble:
Export and import to or from IFC, respectively, is not a round-trip operation. You cannot expect that the model comes back the same way it was at when exported. While the imported geometry is expected to match of the original model's (to a high degree), an imported model will certainly have not the same elements with the same relationship between them.
Where do the errors you shown come from? Are those errors Revit shows? If so, when does Revit show them? When you try to import the previously exported IFC file? Or at some other time?
Thank you
HI,
those errors show as soon as the model opens, however upon closer inspection they appear to be clashing members at a different part of the model. The curved members are vital within the model though (as they make up the entire roofing truss. Do you have any suggestions as to how I could go about fixing this?
Thanks
Hi Billy,
Probably you should post your query into the IFC discussion forum here:
http://sourceforge.net/p/ifcexporter/discussion/general/
As an alternative, you could try my Revit plugin to import the IFC.

I have developed an alternative plugin that concentrates on recognizing advanced aspects of IFC files (in particular IFC4).
If you have problems with this, it would help if you could share a representative IFC file so I can advise.
Many software have also developed plugins for revit to enhance/improve the models imported/exported and if this is available you should also test this.
Note that many software don't utilize revolved shape representations and make it a more primitive meshed object that is not particularly useful outside of viewers and clash detection software. The IFC file size (proportional to number of elements) is a good indicator of this.
Cheers,
Jon
