3The GetPreviewBitmapFile method obtains the axonometric drawing.
You can use ModelDoc2.SaveBMP should save the current view window. You will have to orient/zoom/pan the model to dial in the results. You can also use ModelDocExtension.SaveAs3.
Thank you, I haven’t found an API to preview the front view directly, so I can only use SaveBMP for now.

FWIW I'd be surprised if the previews of the view orientation UI in your example are exposed in the API directly.
