SHX fonts are "shape fonts" designed specifically for CAD software [2†L17-L18]. Unlike conventional fonts found in word processors, SHX fonts use simple strokes to represent characters and symbols. The .shx file extension is unique to this format, which also includes compiled shape files for technical symbols or custom linetypes [18†L10-L13]. These fonts are the native language of AutoCAD and many other CAD platforms, making them indispensable for professional drafting work.
Autodesk AutoCAD, ActCAD, ZWcad, GstarCAD, and other major CAD platforms. Why is Hzdx.shx Important?
When AutoCAD cannot find Hzdx.shx, it usually substitutes it with a default font like simplex.shx . This substitution often corrupts the formatting, twists text alignment, or turns Chinese characters into unreadable question marks ( ? ). Here are the step-by-step methods to resolve this issue: Method 1: Install the Original Font File Hzdx.shx Font
: It is a standard format supported across various CAD platforms, including MicroStation and other Bentley software. Common Limitations Autocad Shx Fonts - MCHIP
SHX fonts are essentially collections of drawing instructions. When CAD software needs to display a character, it follows a series of commands that tell the virtual pen where to move, where to draw lines, and when to lift the pen. These commands include: SHX fonts are "shape fonts" designed specifically for
AutoCAD handles complex Asian languages (Chinese, Japanese, and Korean, collectively known as CJK) using a system called "Big Fonts." Because standard SHX files can only hold 256 characters, Big Fonts are engineered to hold thousands of complex characters. Hzdx.shx acts as a Big Font file to correctly display Chinese text annotations, title blocks, and dimensions. 2. Industry Use Cases You will typically encounter this font in:
If text blocks look like a string of question marks, AutoCAD is failing to parse the double-byte characters. This happens if you placed hzdx.shx in the folder but did not configure the Text Style correctly. Open the STYLE manager, locate the active text style, check the box, and ensure Hzdx.shx is selected as the primary Big Font. Text Extends Beyond Title Blocks These fonts are the native language of AutoCAD
Alternatively, for Windows 7 and later, you can simply right-click the font file and select "Install" [7†L10-L11][29†L8-L9].
Right-click the hzdx.shx file, select Properties , and look for an "Unblock" checkbox at the bottom of the General tab. If it is there, check it, click Apply, and restart your CAD program.
