Section Box for Revit allows you to incrementally move each of the six sectioning planes (Top, Bottom, Front, Back, Left and Right), giving you an immediate visual of your sectioning. You can also select a point in your model to locate any of the six planes. Sectioning can also be done by Level, by Grid Lines or by Rooms.
Note: This app uses a custom installer (and not the standard App Store installer).
Section by Level, by Grids and by Rooms is not available.
