It seems that half the time in Fortress mode, when you aren't building something, you're removing something. Whether that's digging away part of the landscape, tearing down a wall, ripping up a bridge, or just rearranging the furniture, if it needs to get done then it needs to get done.
Although every specific article should have an explanation of how to remove that specific item or feature, if you're here you may need a more basic "how to".
Here's how to remove...
- Main article: Mining
Then, designate an area to be mined. Do this by hitting theesignate ig keys. Then either left-click an area on the same z-level with the mouse, or use the cursor and to establish one point, and move the cursor and repeat to select a rectangle to be dug out.
 Dug ramps/stairs
 A digging "designation"
"Oops"?! Didn't mean to mark that? If the action hasn't been completed yet, don't panic. Use, as above and click over the part you don't want marked.
 Constructed walls, stairs, etc
- Main Article: Construction
If you're trying to remove anything that is a construction (that is, anything that was built with the , keys), that's another designation, use , and mark the construction. Any dwarf will respond and (eventually) tear it down - which takes longer than it took to build.
Construction orders that are not yet constructed can be removed with, , just like the finished buildings.
If it's the movable type, remove as you would furniture, with, .
The latter is just a construction - remove the same as for a construction, above. Be sure, if it's a long floor or wall, that your dwarves won't be standing on one part while a critical part is removed - see cave in.
 A "remove construction" order
"Oops"?! Cancel that removal the same as you would any designation, with, .
- Main Article: Furniture
- Main Article: Workshop
Similar to furniture, use labor, depending on the exact workshop - this can be seen via once the workshop has been marked for dismantling.(or ), and then hit . You'll need a dwarf with an appropriate
 A "destroy" order for furniture or workshops
Oops?! Cancel an order to remove furniture or a workshop by using(or ) then top.
This is trickier, and there are 2 different approaches.
One is to create a refuse stockpile for that class of item (usually remains of vermin killed by a cat, or items left after butchering, but other items are possible), and wait for a dwarf with the refuse hauling labor to find the free time to respond.
A more aggressive and specific method is to create a garbage dump (using the menu) and then mark the items for dumping. Again, this requires refuse hauling, but it can create a quantum dump for any type of item. (Stone is a popular choice.)
- Main Article: Stockpile
Stockpiles can be removed by pressing, and using the cursor keys and Enter to select the area where you don't want the stockpile to be anymore.
 Activity zones
- Main Article: Zone
Activity zones can be removed by pressing, and using the cursor keys and Enter to select the area where you don't want the activity zone to be anymore.
Stones are automatically removed by dwarves with the Stone Hauling labor activated, and placed in the stone stockpiles, or your garbage dump if so designated.
- Main Article: Water
Depending on the quantity and nature of the water in question and the surroundings of your fort, removing water can be performed in a number of ways:
- The most direct method is to either drain it into a lower space, or pump it elsewhere.
- In hot environments, standing water is likely to evaporate, especially in the summer.
- Similarly, in freezing areas you may be able to wait for water to freeze and then mine it out.
- Water in ponds or cisterns will evaporate if it reaches a depth of only 1/7 units. Spread it around by channeling a larger area for it to flow into.
- With careful (and rather labour-intensive) use of water source and pond zones with buckets you can have your dwarves move water from one location to another, out of your way.
- If you've got a renewable source of water (a river, for example), you'll have to get creative with engineering to dam or divert the flow.
- An advanced method, with the potential for lots of Fun, is to combine magma with your water. You can get a lot of valuable obsidian this way, though - see Obsidian farming for more information.
Note: Murky pools will refill when it rains; you may need to take steps to prevent this if you want rid of a body of water permanently.
 muddy floor
After an area has water on it and dries, it will become muddy. The best way to remove this is to have a dwarf with the stone detailing labour activated, and designate the muddy area for "smoothing", via + .
If the stone is already smooth (or if you don't want it to be smooth in the first place), simply place a piece of furniture (such as an armor stand, statue, or animal trap) on top of each muddy tile and the mud will be removed.
Magma is a very dangerous liquid, but it will evaporate exactly like water once it drains down to a depth of 1/7.
Alternately, the addition of water to the magma, even if only at a depth of 1/7, will create obsidian.
Bodies of your dwarves, and their body parts, or bones, will be put into your graveyard, or into individual tombs if that dwarf was assigned to it. Built coffins which have been set to 'Use for burial' will This requires the Burial labor enabled on a living dwarf.
Bodies of everything else, from vermin to Titans, will be placed in the Refuse Stockpile, by a dwarf with Refuse Hauling. If these corpses are unrotten and butcherable, dwarves with Butchery enabled will take them to the Butcher's workshop and cut them into meat, fat, bones, a skull, and chunks. The fat and meat will be used as food, and delivered to that stockpile, and everything else becomes refuse. Bones and, to a lesser extent, skulls can be made use of after this.
Miasma are the gaseous fumes that are emitted from a rotten corpse. They cause nearby dwarves to become very depressed. If exposed to miasma long enough a dwarf will commit suicide.
Good luck removing fire. Water will only remove flames if the object is completely immersed in 7/7 water. Obviously, this is problematic if a dwarf is burning. Your best bet is to isolate the burning substances (clothing, dwarves, beer, etc.) and prevent any dwarves or animals from accessing the banned areas until all the flames burn out.
Creating a cave-in can destroy the burning item completely, which is no loss since it's already burning. (Read up on cave-ins before doing this to avoid worse problems.)
