Editing Mega construction

Note that many of the constructions you see here can also be dug out of natural rock by a [[miner]].  Constructions are different -- they are built by a [[mason]] from a [[stone]] or some other material ([[block|blocks]], [[log|logs]], etc.), rather than carved out of the earth.  Constructions can also be removed by any dwarf, using {{k|m}} - {{k|x}} to designate their removal.  When removed, they are converted back into the material from which they were built.  Their mined-out counterparts cannot be removed in that way.

[[Wall]]s are built by pressing the {{k|b}}, {{k|n}}, and {{k|l}} keys, in that order.  Walls are simply tiles where no one can walk, but can be walked on, provided you are one layer above the wall.  You can build floors off of them and they can be used to close in buildings that are built outside, or even can be used to wall in your fortress from the outside.  Each wall costs one unit of building material.

[[Floor]]s are built by pressing the {{k|b}}, {{k|n}}, and {{k|f}} keys in that order.  They can be walked on, but no constructions (e.g. walls, ramps, etc...) can be built upon them.  However, things such as beds and doors can be put upon floors.  Building a floor above an open tile outside will designate that tile inside,  so furniture could be placed there.  Each floor costs one unit of building material.

Floors are also left behind when you dig a tunnel ({{k|m}}) through natural soil or stone.

[[Ramp]]s are built by pressing the {{k|b}}, {{k|n}}, and {{k|r}} keys in that order.  They can be used to get from level to level of your fortress and are similar to stairwells, but require an adjacent wall to support them.  If a floor is built on top of the Z level the ramp is placed on, the ramp will not be usable.  Each ramp costs one unit of building material.

Ramps may also be dug from natural soil or stone by designating an upward ramp ({{k|m}} - {{k|r}}) on the lower z-level, or by channeling ({{k|m}} - {{k|u}}) into it from the z-level above.

[[Stairs|Up/down Stairway]]s are built by pressing the {{k|b}}, {{k|n}}, and {{k|t}} keys in that order.  Up/Down stairs are most useful inside of buildings/fortresses that span multiple Z levels.  They are useful for replacing ramps in situations where space is more valuable.  They can easily be stacked upon each other to become something like a grand staircase.  Each up/down stairway costs one unit of building material.

Up/down stairways may also be dug out of natural soil or stone ({{k|m}} - {{k|t}}).

[[Fortification]]s are made by pressing the {{k|b}}, {{k|n}}, and {{k|F}} keys in that order.  Your archers are able to shoot their bolts out of fortifications, but liquids and the ranged projectiles of your enemies can also pass through, making fortifications a very [[fun]] addition to your fortress.  However, used correctly, they can be rather useful and productive to your "successful" fortress.  Fortifications are used to protect your archers from the melee attacks of your enemies, while the archers shoot out their bolts unharmed.  However, another equally important feature of Fortifications is the ability to allow [[projectile]]s to pass through them, allowing you to build a catapult behind a fortification and then shoot it at a Goblin Hammerer without the loss of any dwarven life.  Each fortification costs one unit of building material.

Fortifications may also be carved (by an [[engraver]]) from smoothed natural walls.  Press {{k|v}} to designate a wall for smoothing, and then {{k|v}} - {{k|f}} to designate the smoothed wall for carving fortifications. Note that constructed fortifications do not include walkable floors above them, while carved fortifications do (including fortifications carved from constructed walls).
