We are contracted to provide an IFC file on project handover, it is a large science type building with lots of systems family etc. When I attempt to export to IFC it generally crashes, I've probably attempted this 30+ times, using different version off revit and IFC exporter, changing the iFC from 2x3 to others, auditing, changing the detail level to extra low, still nothing works, the 1 time it did run to the end it said it picked up 70,000 errors and had to be aborted, some of these errors where centre lines, ductwork not connected etc. trivial things, is there a way to export and ignore such minor errors, can anyone please advise, we are under alot of pressure to provide this. each attempt takes around 4-5 hours due to the size of the model

Just another note this is a mechanical model with lots of systems , Fabrication Ductwork / Pipework / Mechanical Equipment / Fabrication Containment etc.

Hi Matthew, that is really a huge model and it is likely that we are running out of space in our exporter. One thing you can do is to break the model up in to parts using filters to hide half of the elements (maybe all MEP elements) and export using the option Export only elements visible in view. Then reverse the filter and export the other elements. The two IFC files will be in the same geographic relation to each other.

Hi Andy, thanks for the reply, I split the model into seperate floors of file sizes around 150mb, then exported individually, all worked and have since tested and they come into the correct location.

Hi Matthew.
We often run into the same problem with our MEP consultants on healthcare projects. They handle it same way by splitting the export - but if possible it's prefferable to recieve the files as 'one system per file', not 'one floor per file', for downstream purposes.
