It allows AutoCAD to display Vietnamese characters correctly, specifically designed for Uni-code/VNI character sets in technical drawings. Why it matters:
For Vietnamese designers and engineers, creating technical drawings has long been complicated by the need to display their native language. Standard fonts often fail to render the complex accents and diacritics correctly, resulting in garbled text, question marks, or blank spaces. This has given rise to a "battle of encodings."
TTF fonts are often more aesthetically pleasing and support advanced typographic features. For Vietnamese users, this means that standard Unicode fonts like Arial , Times New Roman , or the open-source Tai Heritage Pro font are becoming increasingly viable for use in drawings, especially in titles, notes, and general text.
Popular sources often include , Cadviet , or Ketcau forums. You will usually download a compressed (.zip or .rar) file containing multiple .shx fonts. Tai Font Vn-uni.shx
If you installed the font but the text still appears broken, AutoCAD might be looking for the wrong font style assignment. Follow these steps to reassign it manually: Method 1: Using the Text Style Dialog (ST)
The "uni" in the name indicates it supports Unicode , allowing for modern Vietnamese typing (with accents) without the need for legacy encodings like TCVN3 (ABC) or VNI. Why You Need to "Tai Font Vn-uni.shx"
If you start a new project today, use Arial or Times New Roman (TrueType fonts). Enable Unicode in your text style. Only use Vn-uni.shx for legacy drawings.
Ensure your system's Unikey or VietKey is set to the correct charset. Fonts with "uni" in the name generally expect standard Unicode input, whereas legacy "Vn" fonts require the TCVN3 (ABC) character set. Switch your input method accordingly to type new text using this font. Best Practices for Managing CAD Fonts : Requires manual placement in the AutoCAD program
Furthermore, in specialized industries like steel detailing or CNC machining, the path-based nature of SHX fonts is often required for engraving machines to follow a single line rather than an outline. Conclusion
is a compiled SHX font file, a format developed by Autodesk. Unlike TrueType fonts (.ttf) which are managed by Windows, SHX fonts are managed directly by AutoCAD, making them highly efficient for displaying text in drawings.
It is widely used to prevent "font errors" (missing characters or symbols appearing as boxes) when opening shared CAD files. 2. Installation Procedures
C:\Program Files\Autodesk\AutoCAD LT 20XX\Fonts Step 3: Copy and Paste Copy the downloaded Vn-uni.shx file. Navigate to the Fonts folder discovered in Step 2. Standard fonts often fail to render the complex
To help find the exact solution for your drawing, please let me know: What are you currently running?
: Without more context, it's hard to say what "Tai" refers to. It could be a style of font, a specific font family, or perhaps related to the Tai languages spoken in parts of Southeast Asia.
Unlike standard fonts (like Arial), SHX fonts are single-stroke, making them ideal for engineering, architecture, and construction drawings where clarity and thin line weights are essential. The Issue:
To resolve missing font errors or to begin using Vn-uni.shx, it must be manually added to the AutoCAD directory, as it is not a standard Windows system font. Solved: Vietnamese font - Forums, Autodesk
