When Revit exports geometry to IFC, it may process it in a way that may lead to loss of information or inefficient data storage. Optimising geometry is highly advised to maintain quick workflows between OpenBIM and Revit. | When Revit exports geometry to IFC, it may process it in a way that may lead to loss of information or inefficient data storage.

This filesize reduction occurs due to two improvements in the IFC4 data format. The first is the new tesselated shape supports, which allow a much more efficient description of meshes compared to the IFC2X3 faceted BREPs. The second is due to the improved support in Revit of exporting parametric geometry in IFC. | This filesize reduction occurs due to two improvements in the IFC4 data format.
