This is about as far as I got with the hand-drawn stuff I was close to giving up and trying a more advanced tool when I discovered Codeblocks. These parts can then be combined into an “object” which can be used, positive or negative, to create appropriately shaped holes in things. The second, after looking into the actual architectural principles of Tudor arches, correctly uses two cylinders for the corners of the arch, a flattened square for the centre, and two more squares to create the doorway and fill in the gaps. Two attempts at a Tudor arch in this system: the first a very poor showing using a rectangle for the doorway, a flattened cylinder for the arch, and a rotated square for the point. So to make a more complex shape, like a Tudor arch, you need to construct it out of other simpler polygons and combine them to make a crenellated tower, you need to create a cylinder, a smaller “negative” cylinder inside to cut it out, and then a lot of little cutout bits for the crenels themselves. Tinkercad is free, web-based, and has one real pecularity: rather than the more common draw-and-extrude model, you can only create “negative” and “positive” 3d polygons and apply them to each other. I got a bit of stick in other channels for this as “baby’s first 3d design package”, but that’s fine because I’m a baby and this is my first 3d design package. I took the lead from a chap on the Mortal Engines server, Alec Matthews (who makes magnificent little models for model railways and is the one who inspired me to get into 3d printing at all, really) and started using Tinkercad. There are an awful lot of 3d modelling tools out there some are free, some are very expensive, almost all of them are quite intimidating. I realised after posting these photos that Walmer/Sandown is actually slightly off scale due to an error in conversions (it should be about 7/10ths the width of Deal.) Ho hum.
