: Obtain a clean copy from a known good installation. Run COMPILE on a valid .shp source if you have it. Problem 2: Arabic Characters Appear Separated (Not Cursive) Cause : By default, Naskhd.shx expects contextual shaping —but some older text objects store Arabic as isolated glyphs because the original drafter used a broken text editor.
To the untrained eye, this error is a minor inconvenience—a font substitution that might go unnoticed. But to a drafter, surveyor, or GIS professional working with Arabic script, the appearance of is critical. Substituting it with a default Roman font (like txt.shx or simplex.shx ) turns elegant Arabic calligraphy into a string of meaningless symbols: ### , ??? , or disjointed Latin characters.

Introduction: A File Extension You Might Have Overlooked If you have ever opened an AutoCAD drawing sent by a Middle Eastern engineering firm, a heritage site restoration project, or a bilingual architectural plan, you have likely encountered a cryptic warning: “Naskhd.shx not found – substituting [xxxx].shx.” : Obtain a clean copy from a known good installation
: Use a dedicated SHX-only text style for Arabic. Never mix SHX and TTF in the same style when working with bidirectional scripts. Problem 4: Plotting to PDF Reverses the Character Order Cause : Third-party PDF drivers (especially older ones like PDF Creator) do not respect AutoCAD’s internal SHX shaping. Characters are exported in logical order but rendered incorrectly by the PDF viewer. To the untrained eye, this error is a
