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)
I have tried using ogr to convert the DGN to a DXF file, but that also
fails to import into this GIS package.
I could write something to pick through the DXF file, but I wouldn't
want to re-invent the wheel.......
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
