[langtitle=fr]Hatches do not appear[/langtitle]

N/A
Hello,
When opening a 25MB .dwg file in SE 2D Drafting ST5, hatches do not appear.
Even if I display all layers, I can't see any.
When I open this same file (Coming from AC1015 (AutoCAD 2000/2000i/2002)) with DraftSight, I can see them.
Even if save in dwg, binary dxf or ASCII dxf from DraftSight, I still can't see hatches when opening it in SE 2D Drafting.
Is this a known issue?
Is there a solution?
Thanks in advance for your help
