Converting STL files to HTML produces empty file

GroupDocs.Viewer Product Family
,
1

Converting the attached STL file to HTML produces a more or less empty file.
(Firefox display it as empty, Chrome renders some placeholder icon)
STL Problem.zip (1.8 MB)

The problem happens with GroupDocs.Viewer 23.1 using this conversion option:
var options = HtmlViewOptions.ForEmbeddedResources(“output_viewer{0}.html”);

The problem does not happen when using PdfViewOptions instead.
I’ve also atteched the output from HTML and PDF generation.

This issue has been fixed. The fix included in 23.3 that is available at NuGet and Releases.

Thanks a lot! I can confirm that the issue has been fixed.

Unfortunately there is another issue now…
I’m getting this exception when using GroupDocs.Viewer:

Could not load file or assembly ‘Aspose.CAD, Version=23.2.0.0, Culture=neutral, PublicKeyToken=716fcc553a201e56’ or one of its dependencies. The system cannot find the file specified.

This only happens, when I use GroupDocs.Viewer (23.3) and GroupDocs.Conversion (23.3.1) in the same project.

It’s because we’re using different versions of Aspose.CAD. The best solution would be GroupDocs.Total as it uses a single version of Aspose.CAD and includes both Viewer and Conversion APIs.

Thanks for the hint.
In the end I can also check which version GroupDocs.Total includes and make sure I have the same ones.

So e.g. with GroupDocs.Total 23.3 I would still have the problem with STL files, as it does not include Viewer version 23.3.

Yes, GroupDocs.Total contains a bit older code, the latest release of GroupDocs.Total 23.3 includes code from GroupDocs.Viewer 23.1.
