I used the following command to convert the `test.dwg` file into an `.scs` file:  
`"D:\HOOPS_Communicator\3rd_party\node\bin\node.exe" "D:\HOOPS_Communicator\quick_start\scripts\easy_convert.js" D:\test_dwg\test.dwg`

After the conversion, I noticed that some Chinese text was garbled.

 ![0000000000000](https://us1.discourse-cdn.com/flex020/uploads/techsoft3d/original/2X/4/418e96c0820675cc2acf1bd8fd8917dbebb8b88d.png)

[hztxt.zip](https://forum.techsoft3d.com/uploads/short-url/sWO9Szto1a4ZMqXSnMJLOCLRFr8.zip) (634.8 KB)

Upon investigation, I found that the garbled text used the `hztxt.shx` font. However, when I opened the `test.dwg` file using AutoCAD software, there were no issues with Chinese text display.

Additionally, I have already configured an extra font loading directory in the `quick_start\scripts\easy_convert.js` script, as shown below:

```auto
const load_all_configurations = "1";
const export_attributes = "1";
const always_substitute_font = "false";
const substitution_font = "SimSun";

let license_key = "xxxxxx";
if (process.platform !== "win32") {
    license_key = `'${license_key}'`;
}

// prettier-ignore
const process_args = [
    converter_path,
    '--input', `"${abs_path}"`,
    '--license', license_key,
    '--output_sc', output_sc_path,
    '--output_scs', output_scs_path,
    '--sc_create_scz', '1',
    '--sc_compress_scz', '1',
    '--output_png', output_png_path,
    '--background_color', png_background_str,
    '--output_png_resolution', png_resolution_str,
    '--load_all_configurations', load_all_configurations,
    '--sc_export_attributes', export_attributes,
    '--prc_font_directories', 'D:/fonts_test/Fonts',
    '--always_substitute_font', always_substitute_font,
    '--substitution_font', substitution_font
];

```

All the font files in the directory `D:/fonts_test/Fonts` were copied from the `fonts` directory of the AutoCAD software installation directory.

Therefore, I am certain that this is a bug in HOOPS Communicator when converting `.scs` files. Can someone please help me with this? Thank you in advance!

Hello,

It looks like you only included the .shx in the zip file. We kindly request that you please send us the DWG file too ― preferably via the [Support Portal](https://partner.support.techsoft3d.com/servicedesk/customer/portal/12). If you don’t have access, you can send me a direct message attaching the DWG file by clicking my profile.

Thanks,  
Tino

Thanks for providing the CAD file.

It’s possible that you are still missing fonts. To confirm that all fonts are being found and loaded, you can use the Converter option [output\_model\_info](https://docs.techsoft3d.com/communicator/latest/api_ref/data_import/converter-command-line-options.html#cmdoption-converter-output_model_info). In the generated text file, there is a section called “File Information” which will list any missing fonts, for example:

```auto
Do you mean to add this parameter "--output_model_info" to print debugging information to find out which font file is missing?

```

</div>

after I append this config option as below:  
`‘–output_model_info’, “debug_20251024.txt”`

the debug information returned in debug\_20251024.txt was:

```auto
DWG/DXF file reader.
Reading data from file : D:\test_dwg\1曲沃中水回用工程工艺施工图20170425_t3.dwg

---------- Reader options --------------------------------------

---- Standard read options ------------------------

Read drawings : Yes

---------- File Information --------------------------------------

Model name : (null)
Version/Release : R15 (2000)
Unit (multiple of mm) : 1

Replace font ￋￎￌ￥ with SIMSUN.TTC
WAR (null) - Cannot load font [.shx]
Replace font ￋￎￌ￥ with SIMSUN.TTC

```

It seems that the “ￋￎￌ￥” font file was missing, but the name of it was garbled, so please tell me what should I do next?  
If there are any errors or omissions in what I have stated above, correct me anytime. Looking forward to your furthure comment.
