Hello.
I'm using Python and OGR to extract the elevation of lines within a DXF file.
--------------
import ogr
driver = ogr.GetDriverByName('DXF')
datasource = driver.Open('test1.dxf', 0)
layers=datasource.ExecuteSQL( "SELECT DISTINCT Layer FROM entities" )
layer=datasource.GetLayerByIndex(0)
for i in range(0, layers.GetFeatureCount()):
layerName = layers.GetFeature(i).GetFieldAsString(0)
layer.SetAttributeFilter( "Layer='%s'" % layerName)
print 'Layer=%s|Features=%s' % (layerName, layer.GetFeatureCount())
for j in range(0, layer.GetFeatureCount()):
myFeature = layer.GetNextFeature()
myElevation = myFeature.GetGeometryRef().getZ(0)
-----------
But I get an "AttributeError: getZ" error when executing it.
What am I doing wrong? Thank you very much.
