I know what you mean Mike, so I just don't do them and try to work around,
But what sometimes helps it to increase the Absolute tolerance in the units properties,
Or in some cases I just scale up a lot, do what I need to do and scale the object down again.
There's actually a technique for doing this, and similar "impossible" scenarios, but it's way complicated, and I only had it explained to me once; not enough to master it. Comes up all the time, though...
