A:Answer You can Save as to PDF. I know Microsoft Office apps can create .pdf files. If your CAD software does not offer a Save as PDF option, you can try using Acrobat Distiller. Yes, Acrobat 2017 can then format the resulting PDF file to the desired page size. I do not know if Acrobat 2017 will run on Microsoft Vista. Please go to Adobe.com then check the supported OS.
