I spent the day being distracted by structure symbols. I went through all kinds of overcomplicated bitmap variations, but eventually came back to simple varicolour vector ones. How do these look?

I might put a black line around them, but I think this is probably a case of more is less. Simple and clear looks a lot better than complicated.

Thank you, Remy, for the clear and concise instructions in the Tome. I had long forgotten how to make shaded varicolour vector symbols.

I will leave them till last and do them as vector symbols instead of bitmap ones. It will be easier for people to make their own personalised ones that way as well.

Maybe this is slightly better?

Or even more discontinuous?

Thanks Quenten :)

A crater sample.

The water in this style is drawn over the top of everything else, like in city styles, so it's easy to add a lake.

I am thinking that the structure markers might be a little too large at this continental scale. What do you think?

For reference, the larger crater is 90 miles (144 km) across.

Have you tried moving the end node of the cave wall section, and while moving it using F9 to snap to the closest node/point on the corridor end?

Or, if you have any experience with the trim tools in the Edit menu, you could try hiding all but the wall sheet(s) and use the tools to trim the ends to each other. Instructions are given in the command line depending on which tool you use.
