IMAGINiT Utilities for Revit: Section Box 

There are two tools in this utility: SectionBox Model and SectionBox Toggle.
The SectionBox Model tool aims to make it easier to both generate and update a series of views that are 3D Sections of the model (based upon the levels of the building).
The SectionBox Toggle utility makes it easier to turn a section box on-and-off quickly, without having to go through the View Properties.
