This is kind of a sign that your project is just not going to work very well - why is it that you need to create such an extremely small detail in your object?

If you are modeling the object for rendering, that is so extremely small that you won't be able to see it.

If you are modeling for manufacturing, that is so extremely small that there isn't any manufacturing process that will be able to generate such a high level of detail.

Why is it that you're trying to create a model that has such an incredibly tiny little arc as part of it?

You would really be much better off not having things like that extremely tiny arc in there in the first place - just have the sides come to a sharp point instead of putting such a tiny arc at the top and your entire project will probably be much easier to handle.

If you do need to create a model with such a huge variation in scale within the same profile, you probably will need to use some kind of specialized CAD program to do it and not MoI - from MoI's perspective that is a kind of strange and not well suited shape to try and build in MoI.
