Font | Hzdx.shx

Unlike standard TrueType Fonts (TTF), Hzdx.shx is defined by simple geometric pen strokes (lines and arcs), which allows for extremely fast rendering in complex drawings.

: A specialized application that can open SHX files and save them as SHP files for editing. This tool is particularly useful for understanding how a font is constructed [32†L4-L6].

When opening a drawing, AutoCAD might ask you to map a missing font. Select a similar Chinese Big Font, such as: gbcbig.shx (Standard Simplified Chinese Big Font) hztxt.shx txt.shx (paired with a Big Font) Using Text Styles ( STYLE Command)

"One or more SHX files are missing. What do you ... - Autodesk

When the missing font dialog box appears, choose Select hzdx.shx from the list of missing fonts at the top.

By default, AutoCAD installs its fonts in the program files directory. The typical path looks like this: C:\Program Files\Autodesk\AutoCAD [Your Version]\Fonts

While TrueType fonts are common in modern Windows apps, CAD professionals often prefer SHX fonts like Hzdx because:

| Font Name | Font Type | Primary Use | Key Characteristics | | :--- | :--- | :--- | :--- | | | Chinese SHX Big Font | General CAD drafting & Financial Documents | Single-line, excellent for budgets/quantities to prevent tampering | | gbcbig.shx | Chinese SHX Big Font | General CAD drafting (National Standard) | The default Chinese font in AutoCAD; standard and widely used | | hztxt.shx | Chinese SHX Big Font | General CAD drafting | Single-line, resembling a small仿宋 (Fangsong) style; extremely common in drawings | | gbeitc.shx | Western SHX Font | General text and annotations | Standard SHX for Western characters; often used as a fallback | | tssdchn.shx | Specialized Chinese SHX Big Font | Structural engineering drawings | Contains structural symbols like steel bar grades; developed by TSSD | | SimHei.ttf (TrueType) | TrueType Font | General-purpose Windows use | A solid, filled font from Windows; richer appearance but larger file size |

: These files are lightweight, allowing complex CAD drawings to load and zoom quickly without slowing down system performance.

For advanced users:

| Font Name | Type | Best For | Compatibility | | :--- | :--- | :--- | :--- | | | Monoline SHX | Dense dimensions; small text | Requires manual install in EN AutoCAD | | Hztxt.shx | Monoline SHX | General notes; better legibility | Ships with AutoCAD China | | Gbcbig.shx | Monoline SHX | Modern GB standard (compliant) | Ships with all AutoCAD versions 2018+ | | Simplex.shx + Big Font | Mixed | Western characters + hzdx | Universal |

In the world of Computer-Aided Design (CAD), particularly within the ecosystems of AutoCAD, ZWCAD, and DraftSight, text style is not merely an aesthetic choice—it is a technical requirement. Among the myriad of shape files ( .shx ) that ship with these programs, one font file stands out as a quiet industry standard for bilingual documentation: .

The distinct design and origin of Hzdx.shx make it particularly suitable for specific use cases:

While less common for SHX fonts, you can also install Hzdx.shx through the Windows font management system:

Open your drawing again. AutoCAD will now be able to interpret the text style associated with this font.

SHX stands for "AutoCAD Compiled Shape File" AutoXchange 2026 Documentation. They are used for both shape definitions and fonts.
