That is a digitising tablet made by GTCO CalComp.

And it is ppf they are using, do as @XPEL Jeff says.
Or if it is, as you say, a one off and you don't anticipate making any more templates, the much cheaper way would be to use application paper over the panel to be templated then transfer to the ppf and trim from there, much like a dressmaking pattern.
