Cause: In AutoCAD text styles, you can assign a fallback TrueType font alongside an SHX. However, if the TrueType font lacks Arabic glyphs, AutoCAD falls back to Naskhd.shx for those characters—sometimes creating a visual mess.
Solution: Use a dedicated SHX-only text style for Arabic. Never mix SHX and TTF in the same style when working with bidirectional scripts.
TrueType fonts rely on OS-level rendering engines (like GDI+ in Windows or FreeType in Linux). Output may vary between printers, PDF drivers, or even different versions of AutoCAD. SHX fonts, including Naskhd.shx, are rendered directly by AutoCAD’s built-in engine, guaranteeing identical output across platforms and devices—a non-negotiable requirement in engineering.
The name Naskhd.shx derives from Naskh (نسخ), one of the earliest and most widely used calligraphic scripts in the Arabic world. Naskh is known for its:
The d in Naskhd likely stands for "Draft" or a specific variant produced by Autodesk or a third-party developer for engineering documentation. There is also a sister font called Naskh.shx (without the 'd'), which is similar but not identical.
Pros
Cons
Final Tip: Always embed or share Naskhd.shx along with your .dwg files if collaborating. Better yet, explode text to geometry (using TXTEXXP) only as a last resort for final non-editable deliverables.

Naskhd.shx is a specialized AutoCAD shape font used to render Arabic text using the "Naskh" calligraphic style. Unlike standard Windows fonts, .shx files are vector-based "compiled shape" files designed for high performance in CAD environments. 🖋️ Purpose & Design
Arabic Script: Specifically created to display the Naskh style, one of the most common and readable scripts for the Arabic language.
Vector Performance: As a native AutoCAD font, it is composed of efficient pen strokes (vectors), allowing for smooth zooming and fast regeneration in complex drawings.
Legacy Compatibility: Frequently used in older DWG files to ensure Arabic characters display correctly without needing modern TrueType fonts (TTF). 📂 How to Install Font Naskhd.shx
To use this font in your projects, you must place the file in the correct directory: Close AutoCAD completely. Locate the File: Find your Naskhd.shx file.
Paste into Fonts Folder: Navigate to the following path on your PC: C:\Program Files\Autodesk\AutoCAD 20xx\Fonts.
Restart AutoCAD: The font will now appear in the Text Style dialog box under "SHX Fonts." ⚠️ Common Issues
Missing Font Error: If you open a drawing and see "One or more SHX files are missing," it often means the original creator used Naskhd.shx and you don't have it installed.
PDF Comments: When exporting to PDF, SHX text can sometimes appear as "comments" or "hidden text." You can disable this by typing the command PDFSHX and setting it to 0.
Encoding Problems: Standard SHX fonts sometimes struggle with the complex ligatures of Arabic. If the letters appear disjointed or backwards, you may need an Arabic support lisp or a specialized text editor plugin.

The Naskhd.shx font is a specific shape-based AutoCAD font primarily used for displaying Arabic text in technical drawings. Unlike standard Windows fonts (TrueType or .ttf), .shx fonts are composed of simple lines (strokes), making them lightweight and ideal for CAD performance and plotters. 🛠️ How to Install Naskhd.shx
To use this font, you must place the file in AutoCAD's dedicated font directory, as it is not recognized by the standard Windows Font manager. Close AutoCAD: Ensure the application is not running.
Locate the Fonts Folder: Navigate to the following path on your computer:
C:\Program Files\Autodesk\AutoCAD 20xx\Fonts (Replace 20xx with your version). Cause : In AutoCAD text styles, you can
Copy the File: Right-click your Naskhd.shx file, select Copy, and Paste it into that folder.
Restart AutoCAD: Once the file is pasted, open AutoCAD. The font should now appear in the Text Style dialog box or when using the MTEXT command. 💡 Key Usage Tips
Fixing Missing Font Errors: If you open a drawing and see a "Missing SHX Files" error, it often means the drawing was created with Naskhd.shx but your system lacks the file. Placing the file in the directory above resolves this.
Mapping to TrueType: When linking AutoCAD files into other software like Revit, you may need to map Naskhd.shx to a similar TrueType font (like an Arabic .ttf font) to ensure the text displays correctly in the new environment.
Performance Benefits: Use .shx fonts like Naskhd for large, complex drawings where speed and portability are priorities, as they load much faster than decorative Windows fonts. 🔍 Where to Find and Download

Naskhd.shx a specialized shape font used in and other CAD software to display Arabic and Persian (Farsi) scripts
. Unlike standard TrueType fonts (TTF), SHX fonts are vector-based "shape" files that define text as a series of pen strokes, making them efficient for technical drawings and plotting. Key Features and Usage : It is primarily used for right-to-left (RTL) scripts like Persian and Arabic within CAD environments. Drafting Standard : Users often pair it with the
LISP routine, a popular tool for correctly typing and formatting Persian text in AutoCAD. Vector Performance
: Because it is a vector font, it maintains precision and clarity when scaled or printed to high-resolution plotters. Installation and Troubleshooting
If you are missing the font or it isn't appearing correctly in your drawings, follow these steps: TrueType fonts rely on OS-level rendering engines (like

The Utility and Implementation of Naskhd.shx in CAD Environments
Naskhd.shx is a specialized shape-based font file used primarily in AutoCAD and other CAD (Computer-Aided Design) software to render Arabic and Persian text. Unlike standard TrueType fonts (.ttf), SHX files are "compiled shape" files that define characters as a series of geometric pen strokes rather than filled outlines. Core Technical Characteristics
Vector Construction: As an SHX font, Naskhd.shx is optimized for plotter-based output. It translates text into precise lines and arcs, ensuring high legibility in technical drawings even when scaled to very small sizes.
Language Support: It is widely used for Persian (Farsi) and Arabic scripts. Because these scripts are cursive and context-sensitive (where character shapes change based on their position in a word), the "Naskh" style provides a clear, calligraphic baseline that mimics traditional handwritten script.
Resource Efficiency: SHX fonts are generally smaller in file size and faster for CAD software to regenerate than TrueType fonts, making them ideal for large, complex architectural or engineering drawings. Implementation and Common Challenges
To use Naskhd.shx, the file must be placed in the software's designated font directory, typically C:\Program Files\Autodesk\AutoCAD 20xx\Fonts on Windows. However, users frequently encounter specific issues:
Missing Font Errors: If a drawing using Naskhd.shx is shared with a user who does not have the file installed, the software will substitute it with a default font (often simplex.shx), leading to unreadable or incorrectly rendered characters.
PDF Conversion: When exporting to PDF, SHX fonts are often treated as geometry rather than searchable text. This can result in large PDF file sizes or "ghost" comments where the PDF reader tries to interpret the geometric strokes as text boxes.
Searchability: Because SHX characters are pen strokes, they are not inherently searchable in a PDF unless specific system variables like PDFSHX are enabled during the export process in AutoCAD. Export unicode text in dxf file into pdf #967 - GitHub
SHX fonts are stroke-based, not outline-based. A single SHX character consumes a fraction of the memory that a TrueType glyph does. In a CAD drawing with 50,000 text objects (e.g., parcel labels, elevation markers, or steel member tags), using Naskhd.shx keeps panning, zooming, and regeneration smooth. TrueType fonts can introduce noticeable lag.
If a drawing is opened on a computer that does not have Naskhd.shx installed, AutoCAD will display a "Missing Font" warning and substitute it with a default font (usually txt.shx or simplex.shx).
