Summary0001936: Dig Designation under Channel removing Ramp
DescriptionIf I set a dig designation below a channel designation, the channel will process first, then the dig designation below it turns into a Remove Ramp designation.
Steps To Reproduce1. Set a channel designation on a tile.
2. Set a dig designation on the tile just below it.
3. Watch as your miner digs the channel, then removes the ramp, trapping himself to die of dehydration.

Channeling doesn't work like it used to -- it produces ramps now. See this discussion for more info: http://www.bay12forums.com/smf/index.php?topic=52685.0 [^]

In that light, I'm not sure this is a bug. What would the expected behavior be, in your opinion?

I know it does. I expect channeling to make ramps. It still does, but the mine designation below it turning into a remove ramp designation throws me for a loop. I was using it to mark what areas would be channeled to on the level below; ironically, it was to avoid channeling down 2 tiles in a row & thus trapping my dwarves.

I expected the Mine designation for that tile to be canceled since it was open (you can travel through it even though it has a ramp). I did -not- expect it to turn into a Remove Ramp designation. I don't know -why- it turned into a Remove Ramp designation. I still need a way to tell where the channeling goes on the level below, though. Hmm...

How about this?

1. Dig designation for a tile is just canceled if that tile becomes open, either from a Channel or a Dig Upward Ramp.

2. In Designation mode, also mark the tiles affected by a Channel or Dig Upward Ramp designation as predicted designations.

Qualities of predicted designations:
-Predicted designations have a different color scheme than actual designations.
-They can't be erased unless their parent designation is erased.
-Actual designations can overlap them (so you can have a Channel below a Channel).

For example:
-Channel: The tile 1 Z-level below a Channel designation will show a predicted Upward Ramp in Designation mode.
-Dig Upward Ramp: The tile 1 Z-level above a Dig Upward Ramp designation will show a predicted Downward Ramp.

This would help players plan complex ramps & ponds, IMO.
