I'm considering making models to aid the photoart development

To do a really accurate photoart piece, you must deal with perspective issues. To a degree, the whole thing can be done by judgment. To increase the accuracy means either doing drawing, building a 3-D model, or building a physical model and photographing it for reference. The last alternative is what is looking like the most feasible way to proceed, in the short term. 3-D models look like the best, long-term approach. The main issue is the learning curve, plus the cost of higher-end tools that support measured models. Tools like Anim8or seem to just be another "eye-ball" approach, similar to doig a photoart piece or drawing without resorting to measuring. In fact, measuring seems to be impractical.
