    Rhino will import a wide variety of bitmaps for backgrounds. I use .png files mostly, changing the colours so the background is grey and the lines are white. Then when you draw over them, you can easily see the black drawn lines with the white peeping out either side, and the grey background is easy on the eyes.

    Scan your images into Photoshop, Paint Shop Pro, GIMP, whatever, clean up using the contrast tools, reduce the number of colours to a few, (you don't need 67 million for this work!) then export as a png file. You can select just the views you want, because Rhino can have a different bitmap in each view on the model. And remember, you can have lots of views, not just the Top/Right/Front/Perspective 4.

    The Sukhoi article covers this in some detail, including positioning and scaling the bitmaps to suit your model space.

    Just checked, it can handle bmp, tga, jpeg, pcx, png, and tiff.
