Some areas are missing when exporting to ifc

[JF.K]

Hi everyone,

We are having difficulties exporting certain areas into IFC. Some areas are missing although they are visible from the export source (Revit). I found the link  https://knowledge.autodesk.com/support/revit-products/troubleshooting/caas/sfdcarticles/sfdcarticles... claiming that it was solved in revit 2019 but its seems that we are having the same issue with Revit 2020.2

We tried:

• workaround suggested by Autodesk (offset the problematic area boundaries so there was not overlapping area boundaries);
• Make an export from the area plan itself floor plan and not 3D view;

We checked:

• workset assignment;
• area type;
• Scopeboxes associated with 3D views;

Everything ended up with the same result. Specific area not being exported (see image below).

Are we missing something here?

Export options: 

• ifc 2x3 coordination view 2.0.

We are using:

• Autodesk Revit 2020.2
• Solibri Model Checker

Thank you in advance

Hi @Rafal.Gaweda,

As you notice by my very late reply I was away from this forum for a while. Meanwhile the project went further and it seems that the issue disappeared. As far as I know all the rooms were able to be exported into IFC, but unfortunately I don't know what triggered and solved the problem.

The addin that you have suggested is not installed in our machines so it wasn't related with it.

I will let you know in the future if this happens again so we can properly track and tackle it

Thank you

Perhaps it had to do with phasing ?

@indiana_j0nes we were modeling in the last phase (new). I am also assuming that no one was changing it since it is a new building with no existing elements.
