Write Face3D Can't Render in AutoCAD

[Lindingdou]

The above code can successfully write a dwg file, but write a three-dimensional surface, when using AutoCAD rendering will appear fatal errors

Is this a common problem, or is it caused by my improper operation.

Thank you. I'll be glad if you can help me. Thank you

Hi @Lindingdou,

It doesn't seem to be related to the Face3D, your implementation looks good there is no issue there, the problem seems to be the switch to the 3D, I've tried to change the view for any file generated by ACadSharp and all of them seem to have the same error for any version after AC1018.

Try to save the file in AC1018 this should solve the issue for now, the needed fix I think is related to the materials, they where introduced after this version and they are not implemented for ACadSharp.

I'll open a branch to try to see if I can find out how to read them.

Thanks for the report!

Thank you very much for your very timely reply. I will try AC1018 again

Sorry to bother you again, I did solve my problem after switching to AC1018, but I seem to have found a new bug, AC1018 version can not display Chinese, all display contents are??？.The switch to gb2312 did not work, and was resolved after switching to AC1032

Here is a similar discussion about this issue:

• Cannot write Chinese text correctly #432

For version older than AC1018 it seems that the special characters are encoded in a different way, here is what I've read from a file saved in AC1018:

Value: "\M+2A7DA\M+2AABA\M+2B575\M+2AB48"

I need to investigate some more about this, but it seems that for special characters in older version the text is saved directly in hex.
