Hello!
Our CNC-Mill is broken right now, so i wanted to manufacture a small bracket per drawing paper print, glueing it to the material and doing it the old way.
I discovered now, that even with the print option "no size change" and with 100% scale, the printing is not true to scale, but loses ~3% size. Tested this with the onshape-generated pdf in chrome and in pdf xchange.
When i measure in the pdf draweing with the tools of pdf xchange, the numbers are correct. But it doesnt print correct.
Does anybody have an idea?

I tested it on the same pc with another printer, a Ricoh SP213W. This one gives me a print with a size of roughly 100.6 %..... so, a small error but still enough at lager parts.
So i suppose the error must be on the printer driver side.
I will search for settings in the drivers later.
I traced it to two things in my case:
On my computer, if I had "full scale" selected in the printer dialog box, it would be off slightly. However, if I hand typed in "100%", it would be accurate.
The second was I was using a browser to open the pdf and print from it. I forgot which browser now, but one browser was printing precisely, and the second was not.
That's madness!![:smile: :smile:](https://forum.onshape.com/resources/emoji/smile.png)
