The Xrev Freebies Suite consists of:
View Box allows you to quickly generate a 3D view around specific elements. This is extremely helpful for visualizing details in 3D when its difficult to understand what is going on in a view. Other uses include creating 3D Shop drawings of particular elements where Autodesk® Revit® Assembly tool cannot, and creating 3D Room Layout views.
UpRev allows you to very quickly apply a Revision to many sheets in one simple operation without the use of Revision Clouds. Apply a Revision to hundreds of sheets in seconds.
Note: This app uses a custom installer (and not the standard App Store installer).
