I started doing my graphics in Inkscape last year.
I create a blank Inkscape document with the enclosure outline. Then I create a layer called 'Template', and I import the page from the pdf with the drill template & line it up with the outline. Before creating any graphics, I print that out and see if it lines up to the board with the pots & switches mounted. If not, I resize the template layer until it is perfect. It can then be used to drill.
At that point it is possible to create the graphics on a new layer leaving the template visible underneath.
Then I know that (if my drilling is accurate...) the graphics will line up with the drilled holes.
