Screenshot attached (very low res unfortunately - all that this website would let me upload)
First thumbnail shows 3D context in which section is taken through a desk , with the desk leg in the near distance, and a cupboard in the further distance.
All items have the same material/hatching definition & thus the same fill is applied in section view (3D hatching enabled in section settings)
The second thumbnail shows how lines are omitted to underside of desk in section where leg joins desk, and even to underside where no elements touch but cupboard is in background.
The third thumbnail shows (just) where the missing lines have to be manually drawn in under the status quo.
The problem is that all three items are 'healed" rather than shown as discreet elements.
Healing is not consistent - see how bottom edge of desk top is inappropriately healed, while the top is not.
Not even spacing elements apart would solve this issue
Possibly the problem is that fills are erratically being "sent to front" by ArchiCAD? - would be good for lines to be always sent to front instead unless "healing" toggled on for that element.
Not shown here is another example in same project, where the fill corresponding to the plinth of a cupboard appears pasted on the far side of a distant wall! - again a hidden line/fill removal issue?
Hope this makes sense
Cheers
