How to set Working Units within a label

kevin b — Wed, 03 Oct 2012 18:08:49 GMT

I modified a simple label to read a particular parameter of an object, in this case the mounting height. I am getting the label to read the correct height, however it is showing in meters rather than inches.

So if the mounting height of the object is set to 4'-0" the label is showing up as 1.2192 and I'd like it to show up as 48.

The Working Units of the project are set to feet & fractional inches and everything else I have shows up as feet and fractional inches. I know there are other labels out there that do similar things and return the measurement in the correct format so I am assuming there is a way to tell the label to convert the units, I just can't find any documentation to that effect. And I haven't been able to find this looking through the other labels.

GDL works in meters internally so if you want some other output, you must do some conversion. Perhaps, these work for you:

nr = 0.345678 

h = 23 !! to move location in example only
TEXT2 0, h, STR ("%m", nr)          ! 0.346
TEXT2 0, h-1, STR ("%#10.2m", nr)   ! 35
TEXT2 0, h-2, STR ("%.4cm", nr)     ! 34.5678
TEXT2 0, h-3, STR ("%12.4cm", nr)   ! 34.5678
TEXT2 0, h-4, STR ("%.6mm", nr)     ! 345.678000
TEXT2 0, h-5, STR ("%+15e", nr)     ! +3.456780e-01  - nan??
TEXT2 0, h-6, STR ("%ffi", nr)      ! 1'-2"
TEXT2 0, h-7, STR ("%0.16ffi", nr)  ! 1'-1 5/8"
TEXT2 0, h-8, STR ("% .3fdi", nr)   ! 1'-1.609"
TEXT2 0, h-9, STR ("% -10.4df", nr) ! 1.1341'
TEXT2 0, h-10, STR ("%0.64fi", nr)  ! 13 39/64"
TEXT2 0, h-11, STR ("%+12.4di", nr) ! +13.6094"
TEXT2 0, h-12, STR ("%#.3sqm", nr)  ! 346
TEXT2 0, h-13, STR ("%+sqcm", nr)	 ! +3,456.78 
TEXT2 0, h-14, STR ("% .2sqmm", nr) ! 345,678.00 
TEXT2 0, h-15, STR ("%-12sqf", nr)  ! 3.72 
TEXT2 0, h-16, STR ("%10sqi", nr)   ! 535.80

alpha = 88.657 
TEXT2 0, h-17, STR ("%+10.3dd", alpha) ! +88.657°
TEXT2 0, h-18, STR ("%.1dms", alpha)   ! 88°39'

kevin:

Also check out the Request functions, from page 293 of the AC 16 GDL Reference Guide:
With these requests, you can learn the dimension formats set in the Options/Preferences/Dimensions and Calculation Units dialog boxes. These requests return a format string that can be used as the first parameter in the STR () function.
