If you are using RISE for procedures and training manuals how do you.....

I would use Rise for online procedures/manuals to be viewed in a browser as a Rise course. 

However, I'd never use it for creating a PDF. Yes, it will export to PDF. But it doesn't export a well-designed PDF. If you want a PDF manual, start with software that's designed for "desktop publishing." 

If you need both online and a PDF? When my clients have needed a PDF of a Rise course (e.g., for compliance purposes), I've just copied and pasted the content into Word, formatted it as needed, and then saved it as a PDF. However, that was for relatively short courses. That'd definitely be time-intensive for large projects.

BTW, you can submit feature requests (e.g., ask for more control of font sizing and spacing) here: Help Us Improve Our E-Learning Software by Submitting a Feature Request (articulate.com). Submitting a request doesn't mean the request will be implemented. However, Articulate is more apt to consider a request made by multiple people.
