denominator of smallest fraction to display

Somebody know what is the name of the variable which holds
"denominator of smallest fraction to display" for architectural units?
Thanks
John

 

LUPREC
LUNITS

?

 

Thanks Jason,
These I know, but LUPREC is for decimal - the number of digits after the
decimal point (it can be set between 0 & 8).
I'm asking for the variable which holds "denominator of smallest fraction to
display" for architectural units - this is something else and it has 9
values between 1 & 256. Generally this is the precision when you are using
architectural units.

I think you are confusing that with AUPREC.

 

No, AUPREG is for angles.
Start the command -UNITS and follow the process - you will see that at one
point it will ask you to set this value. I found all other setting
variables, except this one.

LUPREC
0= whole inches
1= 1/2"
2= 1/4"
3= 1/8"
4= 1/16"
5= 1/32"
6= 1/64"
7= 1/128"
8=1/256"

 

I didn't check, but I think if you're in architectural units, LUPREC is
still used, but it means something like the power of 2 of the smallest
denominator, e.g. if LUPREC is 1, it displays to the nearest half inch, if
it's 8, it displays to the nearest 256th, and as appropriate in between.
But don't take my word for it -- it should be easy enough to check by
setting a fractional precision and typing LUPREC to find out what the value
is.

Great! So this is the trick... Thanks!

Yes, you are right - see below the reply of OLD-CADaver.
Thanks.
