What’s new for IFC Export Alternate UI for Revit 2014 v2.2/ IFC Export Alternate UI for Revit 2013 v1.10:

We did some work to try to make the UI a little more user-friendly.  This wasn’t intended as a complete overhaul, but instead an improvement within the current setup of the alternate UI.  This includes:
1st Page of Export:
– Change default to “IFC2x3 Coordination View 2.0” MVD from “Default 2×3”, which was the original IFC2x3 Coordination View MVD.
– Don’t create an “Update Setups” transaction unless “Modify Setup…” is chosen.
– Move the “Export…” button to the lower-right, next to the “Cancel” button.
– Remove the “Save setups and close” button; setups will be automatically saved when pressing “OK” button “Modify Setup” page.
– Re-order and rename the built-in configurations to match the real file versions and MVD names.
– Sort the table into “included” and “not included” for customizable options.
2nd Page of Export:
– OK button saves configuration changes; no need for “Save setups and close” button.

– Re-group the custom options into more logical groups.
