Set grid divisions

Can the grid major lines be set to 1 inch with 16 inner divisions, representing a 1/16 of an inch.

Unfortunately it seems it is not possible.
LibreCAD is of European origin and doesn't have much focus on imperial units, so some shortcomings in that respect.

Seem absurd that such a fundamental property isn't available.  So much for librecad.

I have to correct myself.
After playing around a bit I have found some way. Set units to Architectural and precision to 1/16", grid spacing to 0.0625.
You can switch to Engineering after that, but the main grid will then consist of 10 1/16" units.
You may experiment yourself a bit with the settings.

    

If you are zoomed out too much so it's too dense for 16 sections to fit into one inch, less are shown. As soon a there is enough space it stays at 16 sections.
