> Via simulations and calculations you can be fairly sure that everything you've thought of will be fine, but there may be things you haven't thought of, and they may prove fatal to the design. I don't deny that, the theorical approach will surely not be 100% accurate. Still, I expect that I would give me thousands of time more confidence than a 3D printed replica. > How do you know that your model accurately represents the earthquake ground vibrations? Because I expect the earthquake simulations in architecture CAD software to be made by physicists that spent time carefully modeling the realistic and complex set of forces that a structure would feel during an earthquake. > How do you know that your model accurately represents the friction? Again, because architecture CAD software are specifically crafted for that purpose, and can theorically simulate the friction and adherence of various materials much more realistically than a mockup 3D printed replica.
