bad extents computing
hi,
i have a file with hatch in strange place, which is not drawn (i don't know why) and it causes that extenst of drawing are computed incorrectly (see zoom extents in odamfcapp 1.12)
acad zooms extents correctly.
regards,

the file i forgot to attach.
attached files (119.0 kb, 18 views)

the hatch (first entity in model space) is solid but has loops of zero square (coincident lines). autocad does not include it in extents. dd includes in extents hatch boundary without attempt to triangulate it.

but there are also loops with positive area
abviewer show the hatch, but it's a mess.
leadtools vector demo show it and it looks like border and text from first layout in paperspace.
both take this into extents.
autodesk volo view does not show it and does not take it into extents.
interesting. i'm wondering why autodesk ignore hatches with some positive-area loops.
regards,
