You can create a local pcb-menu.res (or gpcb-menu.res) in ~/.pcb and
add that to the grid list.

given the 0.01 mill base unit I would like to have a grid of 4 mills.
This would allow 4 mill traces and 4 mills of clearance between traces.
The grid error for 50 mill pitch components would be no greater then 2
mills the grid error for 1mm devices would be under 48 microns (~1.8
mills)

Try this. It allows "um", "mm", "mil", or "in" as suffixes after
floating point numbers (no space between), anywhere an integer is
otherwise allowed. Example:
Line[1.5mm 0 1.5mm 0.5 in 1mil 2mil "clearline"]
Index: parse_l.l

For compatibility, the default (no units specified) should remain 0.01
mil.

I would like a base unit that supports both metric and English units and
that allows me to pick a grid such that the pads of metric parts and
English parts always center (with a reasonable tolerance) upon the grid
Allowing me to snap traces to the grid for boards with both types.

This allows for nm or feet, I like it! add units not confusion!
Remember the high school science teacher docking points for not using
units?
What unit should we define for PCB default units?
They are mill/100, one hundred thousandth of an inch, or a dmil;
deci-mil ha ha a pun for a uni

Please, no more "syntax determines content" patches. If you want um,

Dear All,
Nowadays I find lot of datasheets, in which the dimensions are appear
only in metric system. I don't know whether any of you interested in
creating footprints in mm instead of mil or mil/100, but it was a
nightmare for me to calculate every value from metric to English units.
So I

You can do this as a single project.
But you need to split the plated cnc file up into two files. One file
for your blind vias and a second for the vias that penetrate all layers.
My understanding is that if you do this as a four layer board, the fab
shop will build the
I recently read about having the pcb fab house drill out vias from the
surface to some depth. The article discussed using this technique to
reduce stubs in the Z-axis, but I think it would work in your case too.
I have no experience here though, and can't say if the operation is an
