// Find a candidate 3D view
FilteredElementCollector collector = new FilteredElementCollector(document);
collector.OfClass(typeof(View3D));

Func<View3D, bool> isValidForPreview = v => settings.IsViewIdValidForPreview(v.Id);

View3D viewForPreview = collector.OfType<View3D>().First<View3D>(isValidForPreview);

// Set the preview settings
