Hello @adehuazi ,
Could you confirm whether the JT file loads correctly in the native viewer, such as JT2Go?

If it does, have you tested the JT file using the latest version of HOOPS Exchange? I recommend import the JT file with the default ImportExport sample.

If the JT file is valid and the issue can be reproduced using the latest ImportExport sample, then this likely indicates a bug in HOOPS Exchange. Thank you.

Best Regards,
