Well, yes.

I think there is also another reason that green is used rather than brown. I've got to the point where I need to start adding the... lumpy bits. Where I was starting down the path of making everything a nice brown I realised that the lumpy bits might be a bit offensive in their actual colour. Maybe that is why most artists head for green.

I also modified the cubes after reading a lot of comments here and in the FB Group about how they are practically invisible. I can't make them invisible, but I hope this is an improved representation of them.

The dotty fill is the grey shading. I don't think we have one like that, though I do remember showing a dotty fill on here some considerable time ago. It's not a published fill.

I found it! Wow, that really was a very long time ago. The third one here is probably a possible fill, but use it very small scale so it looks grey. https://forum.profantasy.com/discussion/7039/dotty-fills

Thanks Ede. That's a really neat map :)

I've just got the small drain or central channel connecting symbol working properly, but you've reminded me I need a bridge as well as various planks etc.

Ok, so I got a bit side tracked over Christmas, but I did make a connecting symbol. This is a smaller sewer of a fixed 10ft width between the insides of the walls.

Looks a bit boring, but I've got a whole lot of ideas about debris and creatures on the way.

The larger sewer is still in progress, so don't worry. You won't be stuck drawing everything in 10 ft tubes.
