What hard limits do you mean? Isosurface limitations are mainly the same 
as for other objects, though they may be more vulernable to precision 
problems.

The documentation lists all these limits. Did you even bother to try 
looking it up?

Functions can't handle vectors. You might be able to do this at least 
partially with functions, it depends on how it is done and what you are 
trying to accomplish.
