Getting back into Dwarf Fortress after waiting for the latest version of the Lazy Newb pack. Started a fortress in a good biome with the intent of getting it to Capital status and designing it around Leonardo da Vinci's Ideal City concept - Canals, Sewer systems, multi level terraces, cleanable streets using screw pumps etc.
Embark is 10x10 tiles, with smaller tiles around it for feeder settlements
References because DF crashes when I try to export local map images
Reference #1
Worked out the basic z levels based on the image above: ground is 0z, flat area on the stairs is 2z (using ramps instead of stairs) and the bridge, upper terrace, balcony level for 0z buildings is 3z.
Based on the materials that I have in the embark/using is Granite (Main material for walls, roads etc), Cobaltite (accent colour where ever its red on the reference), Earthenware brick for roofing/filler, Walnut blocks/furniture for peasants/migrants, Cedar blocks/furniture for craftsdwarves/merchants/etc, Mahogany blocks/furniture for nobles/legendary citizens. Steel for grates, fences and menacing spikes for the dry moat. Everything is to be masterwork anything less is sold to caravans.
Class system and challenges:
Bulk of the city will be made up of migrant animal people split into segregated communes (burrows) for !!science!!
Classes are Guests/Animal people, Peasant/Labourers, Crafts/Merchants, Nobles/Officers.
