Zoltan,<br><br>ogr2ogr allows using OGR SQL [1]. You can access the geometry in WKT format and use the SUBSTR function to make reasonable modifications. There are many more functionalities to OGR SQL. Check out the OGR SQL page and see if they help.<br>

I've got a few 3D DGN files that wont successfully read into a proprietary GIS prog, but do read into QGIS (ie: ogr sub-engine) successfully.<br>
I have tried using ogr to convert the DGN to a DXF file, but that also fails to import into this GIS package.<br>
<br>
I could write something to pick through the DXF file, but I wouldn't want to re-invent the wheel.......<br>
<br>
The DGN (hence also the qgis DXF) contains 3D lines. All I need is the line level and colour numbers, and all the vertice XYZ values as line strings.<br>
<br>
<br>
TIA,<br>
