Nope, the Technical Communication Suite makes FrameMaker the driver of content to RH, not ID.
I was told by Adobe sales that we could open an InDesign file directly in RoboHelp. I called technical support on this, but my version of RH is no longer supported, so I couldn't confirm this with them. Makes me wonder.
To my knowledge it is not possible to accomplish. I've been using RoboHelp since 1992 and I've never seen it done.
The only way I can fathom it working would be if InDesign could save as an HTML page. Then import the HTML. Or possibly produce a PDF from InDesign, then import that. But even importing the PDF may not give you the results you want.
