The phase animation is very useful. However, as a Revit user, I think the function is limited by the export settings. Currently, users can only export the model as selected family instances, family types, and categories, so there is still a lot of manual work required to group the objects for animation.
The workflow that I think of is that the user can save a custom parameter in Revit. Then, D5 reads and groups the objects in the scene based on the value of the custom parameter. By selecting each group in the object list, the user can then assign the phase template to the group.
