In the Export IFC dialog, for Save In, navigate to the target folder for the IFC file.
For Files of Type, select the desired file type:
IFC 2x2 (*.ifc)
IFC 2x3 (*.ifc): This is the default certified version of export, and the latest version generally supported by other systems.
IFC BCA ePlan Check (*.ifc): This is a certified variant of IFC 2x2 used for submitting files to the Singapore BCA ePlan Check Server. When exporting to this file type, you should make sure that all room-bounding elements are selected.
IFC GSA 2010 (*.ifc): This is the latest format specified by the US Government Services Administration, based on the IFC 2x3 schema.
Select export options:
Current view only allows you to export elements that are visible in the current view. Visible elements include those that are hidden by hidden line or shaded mode, any underlays in the view, and elements that are cropped from view by the crop region. Elements temporarily hidden using temporary hide/isolate will not be exported. Categories marked as Not Exported in the IFC Export Classes dialog will not be exported. See Loading and Modifying an IFC Mapping File.
Split walls and columns by level allows you to divide multi-level walls and columns by level.
Export base quantities includes base quantities for model elements in the export data. Base quantities are generated from model geometry to reflect actual physical quantity values, independent of measurement rules or methods.
