I'm trying to build a nice, dwarfy waterfall in my main dining hall, which so far resulted in plenty of mudy Fun in my fortress.
I've designed the waterfall well to be surrounded by wall grates, mostly for esthetic and security purposes, but all in all I'm not satisfied with this layout.
The problem is that I can't destroy the wall grates. I can't q+x Remove Building. I can't d+n Remove Construction. Apparently there's no way to remove wall grates (if you don't count massive cave-ins).
Did I miss anything? Is making a cave-in the only option as of .31.25?
