I work at a job where I am continuously using fractions of an inch for measurements and I have tried using plain blender units but its a pain in the butt to have to change it to 16 squares when I want 16ths of an inch and then when I scroll out to inches, I have to count the number of inches because of the 16 squares instead of 12 squares per foot… it would be awesome if we had a customize grid feature in blender where we can set up the grid layers…
for example: a box in user prefs to set minimum grid as 16 squares (16ths of an inch), next grid layer is 12 for 12 inches per foot, then next is 3 feet per yard and so on.
Side note: I was looking at the forums and there are a lot of people that have this same problem with the units. If the blender dev team is tired of hearing this, my idea would end the problem once and for all. Fully customizable grid = no more people complaining.
