sketch or dxf-file from picture (jpg or bmp)

I want to create a gearbox adapter plate to fit a BMW gearbox to a Jaguar XJR engine. Is there a way to create a dxf or sketch-file from a picture taken of the front of the gearbox?
Accepted answer

Use 3d scaner ;)
Or import jpg and put it as an bakgroundfinde 2 points that you know the distens of and scale jpg so that mesure is corect then just put hole and important lines in the rigth spot..
Print in scale 1:1 and cut out papper and check adjust and then send for cuting
