A ramp is a map feature that allows dwarves and caravans to move between levels. Unlike a stair ramps have no 'top', they only have a bottom. The tile above a ramp must be clear for it to operate. Ramps are less useful in construction than stairs because they do not provide access to adjacent tiles on the floor above them. Ramps are the only way that wagons can move between levels in order to access your trade depot.

Ramp Layout

The lower ramp is valid; the upper ramp is not.

A ramp can only be used if it is adjacent to at least one wall on the level below; the level above must also have at least one empty space above such an adjacent wall for the passersby to use. In the diagram, you can see the difference: because the upper ramp is adjacent on all sides to empty space, it cannot be used to reach the tile to the west, although it can be used to reach the tiles to the northwest or northeast of the ramp.

In DF terms, the diagram to the left would appear as:

Construction and Materials

There are two ways for your dwarves to construct ramps. The first is to carve them into the earth itself (see digging), using the ground below or walls of stone, dirt, etc.. The second is to build a ramp out of materials such as stone, wood or blocks or bars.

Digging ramps upwards is useless unless the tile directly above is empty and there access to the side.
- If you are digging upwards through rock, like a cliff, you may want to use a stair instead.
- Ramps are easy to work with when digging downwards through a cliff.
Digging a ramp uses the material and colour of the designated tile.
Constructing a ramp uses the colour of the material used.

Collapse

Be sure to avoid mining out all of the floor tiles surrounding a ramp or staircase above and below it. If you do this, not only will the structures themselves be useless, they'll collapse, both of which can leave your dwarves trapped.

Removing Natural Ramps

Natural ramps can be mined out via the designation menu using the Remove Up Stairs/Ramps selection (d -> z, using the ingame interface). Like the selection says, only upwards ramps can be removed in such a manner. Selecting a downwards ramp in such a manner has no effect. Removing the upward ramp will automatically remove the downward ramp on the level above. The downward part of a ramp doesn't really exist, a creature standing on a ramp tile will be on the lower tile until they move out of the tile.

Removing Constructed Ramps

Constructed ramps can be removed like any other construction via the designation menu using the Remove Contruction selection (d -> n, using the ingame interface). Constructed ramps will leave one stone of the sort the ramp was constructed from.
