Agreed that Back Referencing on drawings titles needs to be enabled for linked markers (it is currently greyed out for linked markers).
Back Referencing only works for detail/worksheet markers if they are placed as a 'source' marker - a source marker only creates a 2D linework drawing.
We use 3D construction details now (which I believe should be the default option for detail markers - as per Reviy and other BIM software); currently in Archicad for example a 3D plan detail is created by drawing a small marquee around required detail area - save as 3D document - then place a detail marker over the same position and link the marker to the 3D document created.
Thanks and apologies for digging up an old thread!
