Another day, and more progress. Today I made the facade texture in Fireworks, using colors from the exterior finish guide. I then started some of the more simple facade features, so far it's all connecting together as it should.
My aim is to get all the more obvious and simple parts done, then worry about finishing the edges, as some of them are very complex, SL is not as accurate or helpful as normal CAD software, and there is a lot of maths to be done to bridge that gap.
