I'm using Helixtoolkit in my WPF project and it seems that Helixtoolkit doesn't support FBX files. So I think I should use the 3D model import-export library Assimp. how can I import an FBX file into my WPF project using HelixToolkit.Wpf.SharpDX.Assimp ? There is no documentation for Assimp.

Hi,@Yasmine_nj . For issues with importing FBX files into WPF projects using HelixToolkit.Wpf.SharpDX.Assimp, it is recommended that you file an issue on GitHub.

You are correct about the lack of documentation. However, Helix Toolkit provides many examples in their GitHub site that can be used to help out. The example that will help you load a fbx file using Helix Toolkit is called FileLoadDemo.

HelixToolkit.Wpf.SharpDX.Assimp does not support .net7. Is there any way to solve it ?
Unfortunately, I ran into the same issue when I had to upgrade my application to .net 7. I made the decision to abandon Helix Toolkit and move over to using ActiViz.Net (https://www.kitware.eu/activiz/). The latest version of ActiViz.Net is a paid product, but it was worth it for the time it would have taken to find a different solution. I combine ActiViz.Net with the AssimpNet (https://bitbucket.org/Starnick/assimpnet/src/master/) to do the fbx file importing now.
