IFC export

[vblevin1]

Is it possible to modify the IFC categories and even delete some? I'm importing the BIM model into Acrobat as an IFC file and some of the categories are just not relevant. And it would be nice if I can change the names. For example instead of "IFCwallstandardcase" I would like to name it "wall"

Have you readd following revit help topics:
To load and modify an IFC mapping file
Specifying IFC Entities for Families
Overriding Categories and Subcategories for IFC Objects

where do I read these topics? In the programs help section?

Yes, Revit help.
