Yes, in selecting a detail for Irrigation equipment, we removed the Edit button.
It's possible to be three dialog boxes deep there (Manager, Edit, Detail Selection), so the only way to edit a detail was to open another session of AutoCAD, which has always had a number of issues.
The more ideal solution would be to force kill all open dialog boxes, and open the detail in the current session. We just thought it would feel a bit disconcerting, so just held off on it.
But I'll get this on the list for us to consider how to get the capability back.
