Default large font configuration
AutoCAD When opening a drawing, if the corresponding large font cannot be found (Chinese font), will use `FONTALT` The font specified by the variable is automatically replaced. Commonly used recommendations `gbcbig.shx` (National standard large font) or `hztxt.shx`.
Repair guide and principle diagnosis
Cause of failure (Why is it displayed as a question mark?) :
Chinese characters are represented by large fonts in CAD (Big Font) Form rendering. When loading external incoming drawings, If the special Chinese font used by the other party does not exist in your local `Fonts` folder (or the replacement is not registered globally), the CAD engine will render these missing characters as `?`.
Manual repair solution:
- Enter in the CAD command bar and press Enter to execute FONTALT System variables.
- Modify its input to specify the replacement large font: gbcbig.shx.
- Save current drawing, close CAD The software reopens. Missing fonts will be automatically mapped to gbcbig.shx, Solve garbled characters.
