Problem with zoom limits

Hi,

In my 3D scene i got a lot of shapes with a lot of details, so i want to zoom many many times to see those details. However the more i zoom, the less the zoom is strong till it not zoom at all, i guess it s due to a pourcentage factor on view.

I would like to know if someone have an idea about how i can make like an 'infinite' zoom that apply all the time the same zoom, even if it s already zoom a lot. Maybe it s simply not possible.

Maybe a trick ?

Thank you for you time!

Nathan
