There was something in Archicad I would like to see implemented in Revit : the possibility to turn any section, elevation or plan in a simple 2D drawing.
There used to be an OOTB extension called "Freeze Drawing" that created a drafting view from any plan/section/elevation/3d view. However it disappeared a few years ago. Some would say "good riddance" as it tended to clutter up a Project file with extra linestyles/patterns etc. similar to an exploded CAD import. I still found it useful for the occasional sketch or diagram
