Facts
Currently only a single Project Base Point is allowed.
Most Design Softwares allow Users to create MULTIPLE Coordinate Systems (UCS).
Scope Boxes have minimal functionality.
Proposal
Give Scope Boxes an Origin, X, Y, and Z axis. Allow the user to snap to these elements.
Include Scope Boxes in options when Linking outside Files, similar to the Internal Origin, Project Base Point, and Survey Point. (See below)
Alternate
Allow multiple Named Project Base Points/Project Coordinate Systems
Scope Boxes could be used in tandem to dictate extents of Views associated with any coordinate system.
Cheers!
