    So does this mean that the Blender World is Flat?

    No, it has to do with the fact that (at least )in C/C++, you have to tell the computer how much memory should be allocated to a certain variable. (Like you can have 8 bit colors , 16bit colors, 32 bit…).

    With numbers this is equivalent to how many digits a number can have…

    Let’s say we give our numbers 4 digits, then in a ‘world’ of 10 meter by 10 meter by 10 meter, when you have a plane of 1meter by 1 meter, you can have distinct points like (0.023, 0.749) for instance.

    When you make the ‘world’ like a cube with size 10,000 meter, then that same plane is just one point (or at the most 4. [Q] Why?).

    When you make the clipping range too large, then Blender (or any 3D software) must make calculations with numbers that just do not have enough precision and rounding errors will get worse and worse!

    This is a bit of a vague description, but I hope you get a bit of a sense of what is going on; no need to know this exactly, unless you’re a programmer;)
