IFC mapping file in Revit

Hello all,

I have one question about the IFC mapping file in Revit.

Could you please someone tell me if I can export building elements that don't have automatic mapping to IFC export classes, so they have the value "Not Exported"? What I should put in the IFC Class Name Column? 
For example I want to export Title Blocks.



Thank you in advance!

Hi @mairh_tsek

 

If needed, the mapping table can be overridden by assigning following shared family parameters:

IfcExportAs: Overrides or sets an object specific IFC Class to which the object will be mapped.

IfcExportType: Assigns a specific Type (Subcategory) within the specified IFC Class.

 

The values used for these parameters are the IFC classes used for the mapping tables as well.

In order to not export a single object type, use the IfcExportAs and type in DontExport.

 

Please see this post HERE and see if any of the recommendations help resolve your issue.

@Viveka_CD ,

 

Thank you for your answer.

 

So, if the element that I want to export doesn't belong to any IFC classes, it is impossible to export it?

Hi @mairh_tsek

 

Can you share a file with us to troubleshoot? I can send you a private folder with you.

We could try different setup to see if the element gets imported correctly.

 

Let me know.

 

Regards,

Hi! @Viveka_CD@mairh_tsek

 

When we create IfcExportAs, is it an "Instance" and IfcExportType is a"Type" in the Project Parameters window?

 

 

Regards,

Arghavan

Hello @arghavan.A,

 

 I think that it is  only works on family types, not instances.

Thanks! you're right. I investigated more, and found that It is only type.
