How can I import a custom shx file?

[mapinxue]

Hi, need help.

Question

I am trying to use ezdxf.odafc to open dwg files drawn with autocad and save them as svg files. However, the files contain existing shx font files. How should I import the font files and export them to svg correctly?

What I have tried

import ezdxf

ezdxf.options.support_dirs = [
    'D:\Fonts' # this Fonts folder has shx files.
]
## ...

 doc.styles.add_shx('font.shx', dxfattribs={'font': 'font.shx'})

The code does not work, what can I do to import shx file and use it?

1. Most options are only read at startup (support folders, paths to executables), changing these values has no effect at runtime. To change these options, you must create a configuration file, see section Config Files.
2. The styles should already be defined in the DXF files (if the DXF file is correct), no need to add these SHX files
3. Adding SHX fonts is done by doc.styles.add('NEW_STYLE', font='new_font.shx'})
4. The add_shx() method handles is a special case, you don't need.
