Stacked fractions being replaced with question marks

Stacked fractions being replaced with question marks

Anonymous

Hello

 

I am in desperate need of some Autocad expertise - at current I am drafting a large number of P&ID drawings using Cad 2012 and we are facing an issue where at random, stacked fractions (eg 3/4") turns into a ?. This is driving the engineers and client up the wall as sometimes these are being missed while the drawings are being checked. It is very frustrating for all involved.

 

I am unsure what is causing this issue, I cant pinpoint a particular user or desktop as it is affecting 5 of us draughtspeople each using the same version of Autocad. 

 

Sometimes the fractions appear as they should, and the next time the dwg is opened, the fractions have been reverted back to question marks.

 

I hope that someone has come across/ fixed this issue before! Any support would be greatly appreciated.

 

Thanks

If you're talking about [plain] Text, and not Dimensions that create their own stacked fractions, nor automatically-stacked fractions in Mtext [though this could be the issue in Mtext not via its stacking capability], that sounds like a potential text-font issue.  Is the font involved one that does not come with AutoCAD?

 

I have seen text fonts in which certain stacked fractions are defined as single characters, with special-character numbers for using them.  If you've changed it to a different font, or if that specialized font is not present and AutoCAD substitutes something else, those special characters will not be recognized, and the question mark will be used in their place.  When you say "the next time the drawing is opened," does that apply when it's opened on a different computer than one on which they showed correctly?  If the problem is restricted to certain computers and does not occur on others, they may just be missing the font.

 

One way to check [whether or not on a computer where the problem occurs] is to look at the text content as AutoCAD stores it, not as it displays it.  Type in:

 

(entget (car (entsel "\nSelect problem text: ")))

 

And look at the resulting entity data list.  There will be an entry like this:

 

(1 . "Text content here")

 

What does that contain in a problem Text object?

Hi Kent,

 

Thank you for your reply to this query.

 

I have entered the command (entget (car (entsel "\nSelect problem text: "))) and have pasted below what Autocad throws back when I select one of the question marks that should display as a stacked fraction:

 

Select problem text: ((-1 . <Entity name: 7ffff611190>) (0 . "TEXT") (330 .
<Entity name: 7ffff608990>) (5 . "10F49") (100 . "AcDbEntity") (67 . 0) (410 .
"Model") (8 . "Level 4") (62 . 7) (6 . "Continuous") (370 . 30) (100 .
"AcDbText") (10 363.88 495.549 0.0) (40 . 3.36003) (1 . "%%132\"") (50 . 0.0)
(41 . 0.714296) (51 . 0.0) (7 . "Style-ENGINEERING") (71 . 0) (72 . 1) (11
366.452 497.229 0.0) (210 0.0 0.0 1.0) (100 . "AcDbText") (73 . 2))

 

 

In comparison, I did the same for a stacked fraction that appears correctly on my drawing:

 

Select problem text: ((-1 . <Entity name: 7ffff60ed50>) (0 . "TEXT") (330 . 

<Entity name: 7ffff608990>) (5 . "10E95") (100 . "AcDbEntity") (67 . 0) (410 .
"Model") (8 . "Level 4") (62 . 7) (6 . "Continuous") (370 . 30) (100 .
"AcDbText") (10 500.023 254.446 0.0) (40 . 3.36003) (1 . "%%129\"") (50 . 0.0)
(41 . 0.714296) (51 . 0.0) (7 . "Style-ENGINEERING") (71 . 0) (72 . 1) (11
502.69 256.126 0.0) (210 0.0 0.0 1.0) (100 . "AcDbText") (73 . 2))

 

Thanks & Regards,

 

 

Zoe

Those are special-character designations, with the leading double percent signs.  [In the kinds of fonts I was thinking about, they would be ordinary characters, in which the stacked-fraction shape has been substituted graphically for the rarely-used character, so this is not the same kind of thing.]

 

Since both examples use the same Text Style, that apparently has a font assigned to it that has one of those defined in it, but not the other.  What is the font?  If it's an .shx font, do you have the .shp file on which it is based?  Does the problem persist with a different font?  When I try those with various fonts I have here, both come out as question marks, but I haven't tried very many -- I might have some that include those.  Do you have any in which both those fractions appear correctly?

You no longer have the required font files for those special characters: which of your users has the correct fonts, where these work perfectly? You all need to get their font files right away.
