Could somebody help me, please, is it possible to make this layout drawing in XeLaTeX?
You could try to do them in tikz or pstricks. It shouldn't be too difficult, but I am not sure if it would be worth the effort especially if you don't know them or/and you are not going to need them in the future.
Inkscape is also an alternative, but (assuming that you are an engineer) a CAD program like the one you suggested would probably be the easiest solution for you - no need to learn something new.
If you need to add annotations at the drawings, in order to use the same fonts with the main text, you can try adding them with tikz
