Channeling under a bridge
« on: October 19, 2009, 05:01:30 am »
Hello all,
So I did something rather silly and didn't think about the consequences (read: playing with magma), and I now have a large number of retractable drawbridges with ground immediately underneath them that shouldn't be there. Unfortunately, even when they're retracted the game doesn't seem to want to let me channel the ground out again. Is there any way to do this?
Thanks

Either A: remove the bridges, channel, rebuild.

Or B: not sure if it would work, but you could try digging out ramps under the bridge, as they remove the ground above them.

I believe that this has been tried, and it failed.  I'm not really awake enough to go look for the thread where this happened, though.

Confirm that ramps don't work.

Christ, are you dwarves or are you elves? If you think Hell has too many demons, then you kill them till the population reaches an acceptable number.

Really...
I swear I have dug Ramps under a bridge but that was from the side, from the side works. But under the bridge itself is considered 'Bridge area' thus can not be channeled or ramped from that are...
But I am sure you can Ramp from the side...

Can't channel under bridges, so you'll have to remove them.

Elves do it in trees. Humans do it in wooden structures. Dwarves? Dwarves do it underground. With magma.

You can remove (some, at least) walls under a raised bridge, though.  Not that this helps you, but it's interesting behaviour.

I've tried channeling through them and ramping up from under them with no success.  Perhaps I should ask a new question: Why did it take almost 3 years for a team of mechanics to attach one lever to one floodgate (all iron, if that matters)? It wasn't as bad with the bridges, but took about the same 3 years to attach all five bridges to a lever, and if I could speed that up rebuilding wouldn't be such a problem.
Thanks for all the help so far

Likely because they were busy with other tasks which have a higher priority. If you want them to go do something RIGHT NOW then remove all labors but the one you want them working on. If they're still not doing it, then they either don't have the material or can't path there.

How far apart were the lever and the floodgate?

If they were in distant corners of the map, it's possible that your mechanics kept getting interrupted by hunger, thirst, and drowsiness before they could finish linking everything up, and each time that happens they have to start all over again from the beginning.

It's amazing how dwarves can make a stack of bones completely waterproof and magmaproof.

It's amazing how they can make an entire floodgate out of the bones of 2 cats.

They were 3 tiles and one Z-level apart, and they didn't seem busy. There was always someone working on it whenever I looked, but not always the same person. I didn't realize they had to restart if they gave up in the middle though. It was a long walk away from everything else in the fortress.

That'll do it. Not only will they constantly get interrupted, but there's a chance some well-meaning hauler will lug the mechanisms all the way back to the stockpile.

Toady, how much of DF is inspired by Labyrinth? Is Armok actually David Bowie? Because that would simultaneously be disturbing and awesome.

Yeah best way to do projects some distance away is to make a stockpile there with all of the materials. I found this out when building my long-ass-wall across the map. It sped up significantly once I placed a stone stockpile near each section and pre-hauled all material out there.

Also the Rock Block road that you're building with just the one Architect (e.g. trying to train him up with something useful) speeds up significantly if you get someone else to take the materials out into the wilds.

(On that map, I generally didn't have problems with thefts from wildlife, due to my inordinate amount of cage traps, for which I had to dedicate a number of Animal Haulers, but I suppose losing the materials might have been a price I would have paid.)

You can never have too many cage traps, best you use the lightest cage you can, fit for purpose of course, otherwise its a pain to load them

which leads me to a helpful point on this topic

the heavier the stuff you are working with cage traps the longer it takes to load and with your stuff being made of iron i imagine that doesnt help with your jobs, but you need quality metals if you are expecting those certain critters I guess, or if you're playing with lava
