I've been trying to figure out how to view AEC objects (aeccland100 objects, specifically) in AutoCAD 2004. I can see the objects in DWG TrueView 2014, but when I convert the dwg to 2004, they are back to proxy boxes. When I try to appload aeccland.dbx, the dialog box says that it is unable to load it. It's not clear from the AutoDesk website exact which enabler I should be using, or how it should function - I've taken a couple of stabs at it, but have no results. Any good suggestions?
