Yet another Grid question K. I'm stumped. I'm building game pieces like walls and doors, etc. I have Units set to Millimeters > Metric > Unit Scale = 0.1000. My game pieces are measured in increments of 1, 2, 4, 8, 16, 32, 64, 128, etc units.

What settings do I use for Grid display so that (as I understand it) grid lines are very 1m and sub-division lines are every 16m. No matter what I change the grid is still seems to be 10x10. Hope that makes sense.
To adjust these, you just need to go to the overlays tab,

and adjust the scale, and the subdivisions to your liking.

I hope this is helpful, happy blending!
