Hi all,

Is there a maximum ifc import file size for Revit?

We are using Revit 2015 to design a large transport terminal. We have been linking the consultant's ifc files in our revit model and it has been working fine. 

Recently some files have stopped linking at all. We also cannot open them in a blank revit file.  The file would start opening and never finish. It would just go to a grey work area.  We can open the ifc in other applications (such as solibri). Its working fine.  The ifc file is about 55 500 KB.  We have been importing ifc files up to 48 000 KB without too many problems.

At the moment we have asked the consultant to split the file into smaller files as much as possible.  Have also looked at 3rd party ifc management  software to reduce the file sizes (without much success).

We have tried doing the previous solution shown in forum:

We can still import smaller ifc files, just not the big ones.

Any ideas? Any work arounds?





note: This thread has also been shown in the Revit Autodesk community forum. Im posting it here too in hopes of finding an answer.

Yep.the solution is:

Work with consultants that only use Revit. Make it a pre-requisite for the asset delivery at the end of the project.

Revit and IFC files are like oil and water. They don't mix. They really do not get along.

Making the files smaller, seem like a good start.

If you were able to audit the consultant's native software model, you may find similar fuckups that occurs in Revit MEP consultant models - namely:1) Consultant needs to purge model of redundant content.

2) Consultant needs to export model objects and review each for size and efficiency and then reduce each one and reload back into their software to reduce the overall model size. Often consultants just receive an object from a supplier like a AHU or pump unit and these are over-complicated 3D models containing hundreds of pipes and nuts and bolts. These can be simplified to basic size and function requirements and still do the same job that they need to do.

3) Ensure consultants' delete all non-3D content prior to export to IFC. All you want is the 3D stuff.

In large models, poor model management is often the cause of excessively sized models.
