after have worked by ADR12 on a pdf drawing (derived from dwg), I would save it (as dwfx file) in Freewheel.
Nevertheless, only my over-imposed corrections appear on the web page (http://freewheel.labs.autodesk.com/......), while the original drawing is missed. Any suggestion?
Incidentally, I use a pdf file because I met problems in opening directly dwg in ADR by DwgTrueView (see discussion opened with ADR group).. How many problems!
If you export a DWF and mark that up with ADR, you should be able to load the DWF into Freewheel. You should resolve the publishing issue so it lets you skip the PDF part.
