Complex geometric building shapes.

Noob question. How did they do it with the clunky josm tools. No way that was done by hand. The spacing between the points are too perfect. Teach me your trade.

Hey thanks. These are my work. I've been on vacation the past few weeks but I'm back.

All the shapes were created in the JOSM editor. Unfortunately there's no easy way to make them... you just have to use the tools very creatively.

Here are some albums that show how these buildings were made:

The tools most commonly used are:

  • orthogonalize shape
  • rotate
  • duplicate
  • make parallel copies of ways
  • create circle
  • join overlapping areas

Let me know if you have more questions and I'll be happy to answer.

And the "a a" shortcut? - "angle snapping active"

This is amazing work. I will look over it and try it out on my cities to really bring them to life. Thank you. You're awesome

Thanks bhj, I just noticed the new buildings in St. Richards. It looks like a really interesting city is coming to life:

Your stuff is great too, wangi. For those who haven't seen Guntrum, check it out:

There's so much interesting artwork being created in this world... and I'm sure I haven't even discovered 90% of it. I hope someday we can start a list of "highlights" (or something) to help showcase some of the most interesting places. I'd love to see what else is out there...

What about creating a "list of highlights" right now?

Or something like a "place of the week"-showcase?

How about this: I create a user named "highlights" and we use that user's diary as the highlight list. The highlights would then appear in the general "user diaries" section but could also be viewed separately at

Anyone could nominate a certain area for inclusion into the list by sending a message to the "highlights" user. It would then be the job of the "highlights admin" to create a diary entry for this (maybe also asking the creator for a short text to provide some background).

I can also create a mailing list, so the "highlights admin" doesn't have to be a single person. What do you think? Any volunteers for the job?

The user "highlights" is a great and simple idea. :)

I would like to volunteer as a member of the "OGF-highlights"-mailing list.
