You can now select objects in top-level x-refs to edit using the Edit Live Section command. A new Properties setting for the 2D Section/Level result will force it to automatically refresh when you open a drawing. In addition, grip states have been added to the Section line so you can modify it.

AutoCAD Architecture generates a 2D section, based on the objects that are automatically included within the boundary of the section line. For even greater control, add and exclude additional objects.
