I am dragging and dropping content from the "design tool catalog - imperial" into ACAD Architecture 2013 and nothing is happening. I don't even get an error message or any indication that a command was processed in the command line history, even when I expand the history with F2.
When you say "dragging and dropping" are you dragging tool palette tools into your drawing area?
You need to drag tool palette tools onto your tool palette, then use the tool from the palette.
You should be able to i-Drop a tool directly into the Workspace and have it work. I am vaguely recalling that there was an issue with this in the past, but cannot remember if it was with ACA 2012. Do you have all of the service packs and hotfixes installed?
