So this is an isometric view. Normally, we see an object with converging perspective lines, where all lines, if extended forever, would converge at a single point in finite space. In 3D CAD, you can switch between various “perspective” views and an isometric view. With isometric views, the true shape of an object is shown with no perspective distortion. Parallel lines are shown as parallel and don’t converge at any single point. It’s kind of similar to what happens with a long telephoto lens. As you get further from the subject, and the focal length gets longer, the foreground and background start to compress together. Isometric projection can lead to some illusions like what you pointed out. But it’s just because our brains are not used to seeing in isometric projection. We expect lines to converge at some point so when we see lines not converge, it can confuse our subconscious.
Example: here’s the perspective view. Note the view cube in the top right corner.
and here’s the isometric view. The view on the view cube hasn’t changed but the perspective shift is significant.
And yes, I’m working on more of the body before working on the interior of the camera body. Because of the way the printer works, when I make the bellows, I still need the camera body to be solid. I can’t have any empty voids in the model or liquid resin will accumulate in them and could prevent the model from printing successfully at best or there would be liquid resin in the model after it prints that can’t be cured at worst.
