what does " i" "mean?

[peells]

We have copied some work from an old project, and are substituting regular M text for multileaders the Mtext being replaces says (E)1i" CW, HW CHR Etc so (E) is existing the i" is a fractional value that I am sure of but which one, Somehow the fractional translated into the i" we also have a s" and r" values, has anyone seen this, and if so do you know what the corresponding values are??

Screenshots and/or actual DWG file that opens at that location would be handy to have around here.

Maybe this chart could be of some help:

 

A fraction symbol chart for old drawings conversion would come handy.

With some research, Autodesk could have something available.

Just curious, where would I find notation like this?

they are older AutoCAD expressions used to translate roman s to another font I believe one of the guys sent me this chart and I am looking into it now, I want to know where this chart came from as well.

While you wait for the correct person to reply... those old SHX font codes are built into each old SHX font by the original creator back in the day 30+years ago at Autodesk.

Are you still using old SHX stick fonts? you'll have to find old scanned copies of old books if you don't find anything online or in HELP in the program.

Thanks for the Screen shot f that chart it did Help as far as getting a base line as to what we were looking at.

And to answer a question about the 30 year + old SHX fonts we may have copied some old ones from a really old project that may have contained them, well it did have them because we found the issue on our drawings.

pendean, No we are not still using those fonts but I know where they came from, it was an old project we copied the work from (really old) and that is where this problem came from, I did figure out what the values were though. they are as follows: i"=1/2", r"=1/4" and s"=3/4" what a pain to figure out, those expressions were all over our drawings.

Those fraction characters date from the days before Mtext, and possibly there was a time even with Mtext before the capability to stack fractions.  So a stacked fraction had to be defined as a single special character.  There are .SHX fonts out there that don't use those %% codes, but rather substitute fraction characters in place of punctuation marks that are not expected to be needed [e.g. typing ^ might give you a 3/4 character, or typing $ might give you 1/2].  "Fixing" those would be harder, because the substitutions could vary from one font to another.

But I write mostly to say:  The quoted line above is not, I hope, to suggest that there's anything wrong with using .SHX fonts.  They have certain advantages over .TTF fonts.

One is in bold-face-ness, such as for emphasis between same-text-height Text/Mtext objects or within Mtext content.  In .TTF fonts, since they define "areas," you get a choice [in many, but not all, fonts] between regular and bold, and that's all.  You have no control over the "weight" of either, nor over how much bolder bold is than regular.  You can have both within the same Style in Mtext, but for plain Text you would need to have two Style definitions if you want regular and bold.  [See the left side of the image below.]

But in .SHX fonts, since they make "linework," you can have any degree of boldness that's available to you.  Using color-based lineweights in plotting, you can have anything within the range of plotted lineweights in your plot style table [the right side -- seven degrees is not the limit.]

Or, if you prefer to use lineweights instead of colors, you have the full range of your available lineweight list:

Either way, those are all possible within one Text Style definition, used in both Text and Mtext.

Also, they are faster to generate.  If you have a whole sheet full of text, you may notice the difference in how long it takes to OPEN or REGEN a drawing.  [This difference used to be much more noticeable back in the days of slower processors, and may not be as much of an issue today, but it could depend on the fonts involved.]
