When using Datagroup Explorer, is it possible to filter only specific elements I've selected in a Drawing View?
Yes, there is a Drop-down list in the upper-left hand corner of the DataGroup Explorer dialog box that allows you to choose from: Show All, Show Used, Show Used (Active), and Show Only Selection Set. The last option, "Show Only Selection Set", will only display the elements you have currently selected for the applicable schedule, even when in a Drawing View.
