I can't remember if I already asked this on the forums or not, but does anyone know of anywhere I can get the Avro Lancaster on autocad?

This will be the best and most accurate way for my build, but it's almost impossible to find as far as I can see. I did find a guy who did the Lanc on autocad, but it was for Revill Germany...they have the rights to it and I didn't get a response from them if I could use it. Thanks in advance.
