Grid line Count only goes to 10,000

I’ve read that on windows the grid line count can go to 100,000.

Or… I wouldn’t be surprised if I’m confused with the grid situation. I want to make a grid that will allow a model that is nearly 400 mm in length. I want the smallest grid lines to be .01mm. That means I need at least 40,000 grid lines. I can’t make my grid go that high. It says it only goes to 10,000 lines.

Pardon me for asking, but why in the world do you need a grid that is 0.01mm?

I know it’s very small! But all my numbers I have for a model I’m making go down to that small, and rather than rounding, I’d love to just use them as is. (It’s a woodwind prototype)

Can you tell me, does your Rhino 3D allow you to have 100,000 grid lines?

Windows V6 is limited to 100,000 lines both ways from the 0,0 origin, so 200,000 x 200,000 or 40,000,000,000 grid lines (40 billion).

Mac V6 will be the same.
