I have a simple test project that I'm creating with an imported Word document (also a simple document - 40 odd pages). I've done this in order to try to troubleshoot why the import isn't correctly creating new topics based on my "Heading 2" pagination setting.
I've come to this (I'm new to RoboHelp) after my first importation attempt created only a single new (top-level) topic. In this case the entire content of the the document was put inside this top-level topic. I finally read enough to find out how RH does pagination/new topic creation on import and so I went ahead and set this in the import Conversion Settings dialog:
However, after running the import again (in a brand new project) I see that there is still only a single resulting topic. TOC, index, etc are all created correctly, but not the topic pagination aspect. Generating the Responsive HTML5 output confirms this since search only ever returns a single result (since everything is contained within a single topic).
