Hi Sylvain,

you could try to test their area and only keep them if the area > 0... ?

Greetings,

   Hi !

I have to transform many DGN V8 files to SHP format (for at leat 4
millions graphical objects) and i get a lot the following error message :
----------------------
Topology Creation: The input feature (which claimed to be a polygon)
consisted of only 2 identical points and had zero length and area, so it
will not be considered during topology creation.  It's coordinates were:
 Coordinate #    0:              570182.71             243977.695
 Coordinate #    1:              570182.71             243977.695
----------------------

How can i filter these invalid polygons ?

Thank you for yourt help

Best regards
