By the way, non Revit non ArchiCAD are showing markers correctly. According to USA National CAD Standard needs to be shown only one marker (as datum) - first floor I guess. Rest - just dimensions.
In Europe shape of markers is different - not the circles with cross.
The problem with the markers in ArchiCAD, that they don’t have editable hotspots. When I created my own markers, I used object, that needs to be placed in section.
