How to add imperial inches in command line?

Hi,
Taking measurements and needing to enter Imperial inches into command line, as steel tape measures are still in Imperial Inches/cm combinations.

How does one enter e.g 123 17/32 inches into the command line when wishing to make a dimension that long ?

secondly if I have to measure a length in two parts, how does one make a dimension arrow by entering 32 17/32 + 64 5/16 ?

If anyone knows of a locking steel tape measure that has a rubber inset into the plastic lock lever to better grip the steel tape, and truly LOCKS the taoe even after years of service and has decimal inch along one edge and mm along the other, please let me know the model name and number !

Steve

use a hyphen…

123-17/32 

or

10'3-17/32

You have mentioned this work flow quite a few times now and I always wonder why you want to make a dimension of something that isn’t drawn yet. if you need a certain distance, why not just make a line of that length?

Hi,
Cheers Jeff,

Wim,
you are saying make a line of length 32 17/32 + 64 5/16 then create a dimension snapping to its length then delete line.
How does one enter those two values to create a relative end of line ?

R32-17/32+64-5/16,0 and hit enter sees unknown command.

Does anyone know of inch decimal (12 inch to 1ft) and cm in a locking steel tape measure ?
Is everyone entering inches as fractions into CAD and hand held calculators ? The latter if basic models have no ability to do so, yet such tapes are still in fractions. Seems archaic. Are folk still measuring and remembering in their head until they get to write it down, then convert it to decimal using a calculator to draw it on their decimal site visit notes, 34 and 17 thirty tooths !, 63 and seven sixteenths and so on.

Cheers
Steve

Tajima makes a few… they’re the ones named 25/7.5, 16/5, 33/10 (feet/meters)

pretty sure Stanley has a few models with imperial/metric as well.

[edit] actually, that might not be what you’re looking for… what do you want? a tape with decimal inches as well as centimeters?

many people have 16ths memorized as decimals… .0625, .125, .1875., .25 … etc.

i also use a phone app which allows feet/inches/fractions to be entered…

there are also stand alone calculators which do this… places like home depot sell them.

measure and write down as you get the numbers… pretty sure something won’t fit right if you depend on memory until you get back to the shop :wink:

depending on the circumstances… i’ll often use rhino (as in, laptop open while surveying) and just model the site as i get the measurements.

to be honest, i’m not exactly sure where you’re encountering problems and i don’t think my suggestions are really pinpointing your issues.

that said, in rhino, you can enter dimensions that don’t coincide with the file settings… for instance, if i’m using the template ‘small objects -millimeters’, i can draw a line using:

11-5/32" 

as my distance and it will draw to proper length… then i can measure the length using the file units and it will show me the length in millimeters… just because my file is in millimeters doesn’t mean i have to convert my imperial dimensions to metric prior to entering them… rhino will accept all formats regardless of file settings.

(just in case you weren’t already aware of this)

likewise, if my file is set to feet&inches, i can enter 14.3cm for a length and it will be drawn properly.

Hi,
I am onsite measuring items manufactured 70 years ago to decimal inches, so to have a tape measure marked out in decimal inches , rather than have to look at it and think, ’ I reckon that would have been 1.1inch’ when its near 1 1/8 on the tape measure, is what I need, then its easy to go back home and draw it all up in CAD entering 1.1 not 1 3/32 into the command line. To measure an item built to decimal inches one needs decimal inches tape measure, to measure an item built to metric, best use a metric tape measure. For some reason imperial exists only in fractions, I guess carpenters and DIY are the market. Even so adding up decimal in the head, is easier than 3/32 and 5/16 and 5/8 and 15/32 and so on.

also easier adding up decimal on a calculator !

On site I dont have time to keep switching between tape measure and another gadget, especially not a laptop etc, every second counts and its fast fast fast measuring with clipboard.

Back at base, in Rhino, if I draw a box and use R1.1,3.2 for the second corner, it works, rather than enter R1-3/32,3-3/16

as mentioned though R32-17/32+64-5/16,0 and hit enter sees unknown command.

i.e if I have two dims making up the x distance for an Rx,y command line entry, how should I enter them ?

Be that for either drawing a dimension line or drawing a straight line then snapping a dimension to it.

There are also conversion charts for all the dimensions . That may come in handy.

Steve, did you know that the / symbol is used as a divider too? If you want to convert 3 inches to 1.5 radius. Use the / Symbol. Or if your stsrting a line for both ways , you can type the whole distance and / 2 and it halves it boyh sides of midpoint. Sure is hard to type on phone.
