You can use the Print function in CreoView to print to Adobe PDF, if you have it or another PDF 'printer' installed.
You can open the file in Creo and Print to PDF.
The only way I know how to do something like that is to get a problem like PDF reDirect installed on your computer. Then in Creo View you can use File > Print (or Print Preview) and change the printer to the PDF reDirect.
I should have worded it differently, I have Creo 3, I was asking if there was a way to save as a PDF from Creo View because sometimes I need to send a copy and I don't want to add it to a workspace just to open it and save as "quick PDF."
