Problem:

I have some OpenBuildings Designer properties that I do not want to export to IFC. How can I remove those properties from the IFC export process?

Solution:

Generally all the DataGroup properties associated with any element in OpenBuildings Designer will get exported to IFC. The IFC Export settings are stored under the Dataset_XX/Setting folder. Inside the folder, there is a file named IFC_CV20Filter.set that can be used to exclude specific properties. Here we will exclude the StructuralFramingCommon, Pset_PileCommon and Fire Resistance properties from export to IFC, so we will use a text editor to add the following lines at the bottom of the file.

EXCLUDE_PROPERTY_SET
Pset_PileCommon
StructuralFramingCommon
"Fire Resistance"

Once you have added these lines, save the file and then export to IFC and you should see that the properties above are no longer included.

Attached is the modified .set file above along with an example DGN and IFC file.
