I’ve been using Blender for the past 4 years or so. I just realized that I have absolutely no idea how things work when it comes to sizing. More specifically, the overall scale of a given model.
For instance, say I’m modeling the interior of a building with many hallways, doors, rooms, etc. Is there a certain reference measurement I should be using to ensure that everything will be “to scale”. Not in the literal sense, of course, but more in the sense of how lighting comes into play, ease of use navigating the model workspace, etc. Will everything translate and behave the same regardless of what size the model actually is? It seems that lighting will differ based on the size of your model, but is that the only thing affected? Any advice would be greatly appreciated. Thanks in advance.
physics and such are affected, if you’re using them. i.e. you put in 9.8 for gravity, objects will fall ‘faster’ if everything is scaled to smaller sizes.
press enter to unzoom your perspective. Now every the dark grid lines are called Blender Units. Each one is 1 meter. (of course they could be anything, but most people call it a meter
The Blender coordinate system is exactly that: an abstract coordinate system, nothing more nor less. It has no connection to “the real world,” unlike (say) a CAD system.
Obviously, if you are modeling something “in the real world,” you need to agree (with yourself…) upon some sort of mapping that you will use between “coordinate numbers” and “real-world measurements.” It does not matter what you choose as long as you apply it consistently.
