Hzdx.shx Font May 2026
A single manufacturing drawing might contain 10,000 Chinese characters. TrueType fonts treat each character as a complex mathematical curve (Bezier spline). SHX fonts treat each character as a series of straight lines and arcs. In large assemblies, SHX fonts load instantly, while TrueType can cause a 5-10 second lag when panning or zooming.
| Problem | Likely Cause | Solution |
| :--- | :--- | :--- |
| Text shows as ??? | Hzdx.shx missing the character's code page mapping | Switch to HzTxt.shx or gbcbig.shx (Chinese Big5) |
| Font replaced with simplex.shx | Missing Hzdx.shx on someone else's computer | Use ETRANSMIT to include the SHX file, or convert to Mtext → Explode (not recommended) |
| Vertical text overlaps | "Vertical" option turned on incorrectly | Edit the text style → turn OFF Vertical |
| Thin lines when plotting | SHX fonts plot at actual vector width | Set LWDEFAULT or use CTB/STB plot style to add lineweight |
| Slow performance with many text objects | SHX font is actually large (rare) | Use TXT2MTXT to combine single-line text, or purge unused text styles |
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: Hzdx.shx. Hzdx.shx Font
If you have ever opened a mechanical drawing from a Chinese manufacturing partner or a civil engineering plan from an East Asian firm, you have almost certainly encountered this font. But what exactly is Hzdx.shx? Why does it refuse to display correctly on your Western version of AutoCAD? And how can you troubleshoot the infamous "Missing SHX" error?
This article explores the technical specifications, historical context, and practical applications of the Hzdx.shx font. A single manufacturing drawing might contain 10,000 Chinese
Hzdx.shx is not included by default in standard English-language AutoCAD installations. It is typically bundled with:
When a Chinese drafter sends you a .dwg file using Hzdx.shx, your American/European AutoCAD doesn't have the file in its Fonts folder, so it substitutes a garbage font—usually displaying Chinese characters as random question marks (????) or ellipses (...). When a Chinese drafter sends you a
You will often hear Hzdx.shx mentioned in the same breath as Hztxt.shx. They are siblings. While Hztxt.shx (Horizontal Text) is used for standard paragraphs and notes, Hzdx.shx is optimized for dimensioning. The "dx" suggests a more condensed or "Drafting X-height" variant, meaning the Chinese characters are slightly narrower and align perfectly with Western single-line text styles like Simplex.shx or Txt.shx.
If you have a valid copy of the file (from a legitimate CAD software bundle or a trusted colleague), here is the safe installation process for Windows:
