first of all.. i will show you my setup:

1 unit = 1 meter (need that for an other program to make levels for games

display unit scale = meters

grid and snap settings:
Grid spacing = o,1m
major lines every nth grid line = 10
perspective view grid extent = 10

my problem! i can create a box of a meter by meter no probleem.. but when i want to zoom in to create smaller objects... it disappear in my perspective viewport...

does anybody know how i can fix this?
what is a must is that 1 unit has to be 1 meter.. because of other program.
