If you designate an Up Ramp on a tile below your current level, and order your dwarves to dig out a room around it, they'll do it fine.

If you designate an Up Ramp on your current level and order your dwarves to dig out a room around it on that level above you, they'll dig out the ramp but will not do anything else.

You can't designate an ramp on a already mined tile. However you can construct one via: [C][r].

I know. This is a pathfinding issue.

code:

z
#####
O...v#
#####
z-1
#XX
#^X
###
# = unmined rock
. = floor
X = designated for mining
^v = ramp
O = a dwarf

Here the miner will go and mine out the tiles fine. However:

code:

z+1
###
XvX
XXX
z
######
#^...O
######

The dwarf will not mine the designated tiles for some unknown reason. Possibly a pathfinding error.

Mmm, I had exactly the same issue.

Another (potentially related?) problem I had with ramps and pathfinding was if I dug out a tunnel and put a down ramp at the end, then on the level below did a U-turn and started digging back in the opposite direction. I then couldn't build any structures on the lower level, because it claimed there was no path to the construction materials.

I don't think it's a pathfinding error so much as it's a quirk with the way the game treats ramps.

While you are standing on a ramp tile, you are always on the lower level.  As soon as you step *off* of the ramp tile towards the direction of the higher elevation, then and only then are you considered on the higher level.  Ramps must be built on a lower level adjacent to already-clear and open spaces in order to be used.  You can dig down with a ramp, but digging up requires a stairway.

Now, logically speaking, digging a ramp up should of course be possible, but it's just a quirk with the way the game handles the different elevations right now.  Stairs work fine in the meantime. =)

Ramps only work well outside for me. I stick with stairs for inside areas.

I haven't tried this yet, but if you use stairs a first to open the level above then remove the stairs to replace them with ramps, it might work.

Hrm, I think they used to do this properly, but there are so many permutations I can't be sure, anyway, I'll take a look at it.
