These are two interior elevations I made. The crop region for the one on the left is good but it's floor is flush with the sub-floor (and level). The crop region for the view on the right is bad, too short because the finish floor is set so that it sits on top of the sub-floor. Quirky quirky.
I made a video to demonstrate the issue, embedded here.
The video is based on Revit 2015 R2 and Update Release 5 installed.
