Hi @Lian,

I don’t believe this method is implemented on Rhino3dm on macOS.

System.Drawing.Bitmap tf = File3dm.ReadPreviewImage(adres);
Rhino8 MacOS I’m not getting any image either.!

System.Drawing.Bitmap tf = Rhino.RhinoDoc.ExtractPreviewImage(adres);
also doesn’t work for MacOS. Rhino8 sr6

@taraskydon - yes, these are known issues.

It works for Windows. Like Rhino.RhinoDoc.ExtractPreviewImage and File3dm.ReadPreviewImage.
it’s the only thing that works. for macOS. System.Drawing.Bitmap tf = Rhino.FileIO.File3dm.Read(adres).GetPreviewImage();
but this process is too expensive to process if I want to download a lot of files. :pensive:
