Once upon a time, I was furious with my 4th grade science teachers for teaching me LIES... the Niels Bohr Model of the Atom, bringing coathangers and styrofoam balls to school on the bus when TRULY the atom was an electron cloud of probabilities, etc. etc. All that time wasted, all those coathangers and styrofoam ball USELESS because that wasn't what was really going on. Cue several years later and I'm trying to model my kitchen in sketchup to figure out if something is going to fit, or if some remodeling project is worthwhile or even feasible. I start measuring and modeling the countertops, and question: do I need to account for the countertop overhang, or can I just treat them as cubes? I needed the overhang. Do I need to account for the "toe-kick" (cutout where your feet go instead of banging the cabinets)? Maybe? What about the cabinet doors? Further: what about the inlays? The handles? What about the insides? The supporting structures, the screws and studs? I then thought back to the humble "Niels Bohr Model of the Atom" and forgave my teachers, because I had just then realized: "A model must be just good enough to be useful, and sometimes too much detail isn't helpful (or useful)" It's an extremely useful perspective to have: First decide the utility (the questions you'd like to answer) and then choose the most effective ROI to get there. Further: having varying levels of "zoom" or detail with different acquisition, maintenance, or usage costs isn't out of the question!
