It's generally not a good idea to have objects with very large coordinate values in them.

It tends to degrade the precision of arithmetic done with floating point numeric values.

So don't set up things like an object 100,000 units across with units = mm, it would be better to use meters for the units or have the model at some scale factor instead of having very large or very small numeric values.
