It's really great. I can't wait to have an opportunity to map with this style.

Thank you! I was fiddling around with various things like drawing a circular building with 32 side and then layering a Solid 10 transparency with an inner edge fade, but it didn't quite work out the same as the Hachures. Appreciate your help very much!

Didn't have a chance to follow the PDF yet but in the meantime, here are two approaches using three concentric rings of 16 panels per ring. The top is a solid fill and the bottom is a light blue set with a 20% opacity. (Copying in a circular array sure saved me a lot of time here.) Also haven't had a chance to experiment more with the Ball.png filter.

Now I'm thinking my dome might be flat panels welded together (with metal seams) rather than a proper ball. Hmmm. It's for an observatory.

(My plans are delayed a few hours so I got back here faster than expected.) I do have City Domes and I love it! Many months ago I bought that annual specifically for City Domes (and then like all of my other Annual purchases, discovered many other things I love about that annual.) But this is a commission that doesn't give me any leeway beyond DD3.

But good tip about the Humble Bundle! What a deal. I happen to already have everything except the Tokens, but I highly encourage anyone who doesn't have everything to take advantage of it.

Continuing my experimentations. Figured out that donut-shaped circles cut into slices aren't proper polygons that respond to the Angle by Edge function. I will have to try manually tracing/drawing my pie slices.

I used to work for a community-written search directory. Never underestimate the power of intangible psychological rewards! They work on me. 😉
