Last night I read a post by Jay B. Zallan regarding scope boxes plus I just went through this subject with a few folks yesterday.
All of which reminded me that I wrote something ages ago while I was working at WATG. The pdf's are shared in the AUGI Tutorials forum (have to login to download them).
Here's the preface of the pdf:
The purpose of a Scope Box is to limit visibility of datum to a specific portion of your project.
Scope Boxes actually go a little further by:
• Automatically controlling the extents of a view’s crop region and orienting the crop region to be aligned with the scope box boundary.
• Automatically and globally affecting the length of “their” levels, grids and reference lines when the scope box boundary is changed.
• Effecting change vertically as well as horizontally (you can isolate specific floors or areas within a bldg)
• Hiding annotation for other related views (Sections/Elevations) if the cut plane of that view is not within or does not cross the scope box for that view.
Three concepts apply to scope boxes: (Also see the Sample Scope Box project file)
• Creating a Scope box
• Applying a Scope box to datum and views
• Controlling the visibility of Scope Boxes
I too really like using them to manage a consistent cropped boundary for multiple floor plan views.
