When I create a pdf by doing "save as/.pdf" all the thicknesses of the plan are exactly the same. (and I checked the box "Use the line weights of the specified printer" in the option)
Whereas when I go through "print/PDFcreator" the thicknesses are good.
"Well then use PDF Creator!! "You will tell me! ^^
Except no, it takes a lot of time, unlike "save as/.pdf".
