I have software at home to convert any file (including AutoCAD) into PDF files.
www.pdf995.com
I have not had any problems using it. If you do pay (I think) $25 you don't have to put up with the sponsor pages.
Hope this helps.
When selecting an item (such as text)then right mouse click and obtain the properties dialog box.
I then click, in say, the text height to change my text height but after second ot two the box is no longer active.
So I begin typing (while looking at my keyboard) then look at the dialog box once...
