I second this. I used Cosmographer deckplans for vault-like maps to recreate Gamma World maps.

You could perhaps also use SS3 Modern Blueprints to make maps like this:

If I could make a suggestion, I'd love to see a sci-fi/deckplan style for Perspectives 3.

Lol, typical void catto behavior. ;)

Fixed some minor mistakes and spelling errors.

Finished a few more maps, this time from the 3rd edition Lords of Darkness source book.

Haha yeah I can relate to that. Some of the maps I finished after the fact. Now that I've developed a workflow and 99% of the work already done I can convert FRIA maps fairly quickly. Also trying to stay as faithful to the original maps was a good choice in hindsight, I saved a lot of time keeping maps sparsely decorated with symbols.
