In search of a maneuvering board

[Omawari_San]

I recently reinstalled SH5 and enjoy it on 100% realism.
But I don't like plotting lines with my mouse. I would prefer a maneuvering board, where I can do all that stuff with a pen.
Is there a file in a reaonable solution to print it on A3? Preferable with metric scales?
I just found an english maneuvering board with an imperial scale.

But it is in some sort of Sketchup program file format:

There is probably a way to print it. I never used it myself though.
