two ways of exporting as pdf, either print>pdf or select curves then file>export selected and choose as pdf.
the latter decides to put my two items half off page and add in items I had not selected.
The former I can move a window and then make sure scale hasnt changed. I get just the selected items.
why is export as pdf doing this ?
I use pdf24 assistant from pdf24.org its rhino though doing the selecting of unselected items as I see these well before even invoking pdf24 !
