When exporting an Archicad layout with drawings to Autocad in "paper space with cropped view content" mode (preferred by most Autocad users I work with) very often a display order mismatch occurs - especially in complex sections and elevations: lines in model space which must be visible are hidden under other 2d elements ( most frequently Autocad wipeouts which could be subject of whole separate topic). So it is necessary to change manually their display order (draw order in Autocad) to obtain the correct look. This is time consuming and unreliable for any person without special Autocad skills.
A partial solution is to break the drawing link to its internal view source. Then the diplay order is perfect. However, a terrible mismatch in line types and linetype scale occurs almost inevitably e.g. line which must be dashed becomes dotted etc.
