It’s a sad reality that creating models with new tools like the Cricut leads to more time in front of the computer. What’s worse, my wife and kids are never even feign enthusiasm when I show them the output of a night’s drawing. I doubt you are interested either.
The partially tested plan is to make the roundhouse walls from six layers of card, and the photo above shows all those layers visible at once. That is a bit like trying to make sense of heap of spaghetti, but I think it almost illustrates the manner in which the layers are drawn. To create this drawing in Inkscape, I started with a view of the exterior walls that I was shooting for. I then duplicated the layer six times, once for each layer of card. On each layer I removed all the exterior elements that don’t belong, and added the interior elements that do belong. There is a special layer called “Annotations” on which I keep notes to myself and some key dimensions.
Before loading them on the Cricut, the layers need to get flattened, and each set of shapes that will be cut together needs to become a single path. Here are the six layers of the test end wall laid out for cutting.
