Line thickness in PDF files

Question:

Why are the line weights so heavy when creating a PDF? It really makes the schedule hard to read and is not good for presentations. Is there something I can do to fix this?

Answer:

Yes!

Do this:

Choose Tools | Program Options | Edit.
Do not attempt to adjust line thickness on PDF files.
Automatically adjust filled pattern sizes when printing. This will prevent the software from attempting to adjust the line thickness.
