Ryan, could you please explain why you want to disable the above if statement ?

This code crashes on Yemen (Tiles\N12\E044\201_RoadNetwork\L00\U0\N12E044_D201_S002_T003_L00_U0_R0.shp). It is trying to get the CNAM attribute, but from an extended attribute DBF file where one doesn't exist. Since it wasn't converting correctly anyway, I disabled it.

dbfTableName = getExtendedAttrTableName(shpFilename)
RelatedTables.createRTESchema(sqliteCon)
relationship = RelatedTables.Relationship()

## Converter Procedure

* Software Installations
* Download and install python 3.7 (I think the script was tested with 3.6, but 3.7 has worked good)
* https://www.python.org/ftp/python/3.7.2/python-3.7.2-amd64.exe
* Download and unzip GDAL executable somewhere on disk (if you don’t already have it)
* http://download.gisinternals.com/sdk/downloads/release-1900-x64-gdal-2-4-0-mapserver-7-2-2.zip
* Download and install the GDAL python package
* http://download.gisinternals.com/sdk/downloads/release-1900-x64-gdal-2-4-0-mapserver-7-2-2/GDAL-2.4.0.win-amd64-py3.7.msi
* Download and install the dbfread python library
* https://files.pythonhosted.org/packages/4c/94/51349e43503e30ed7b4ecfe68a8809cdb58f722c0feb79d18b1f1e36fe74/dbfread-2.0.7-py2.py3-none-any.whl
* python -m pip install _pathToDownloadedFileAbove_
* There is probably easier ways to install these python packages, but our work internet breaks the easier methods that auto download and install
* Running the converter
* Add the GDAL bin directory in the path (first, in case other programs have older versions of GDAL)
* set PATH=_gdalBinDir_;%PATH%
* set GDAL_DATA=_gdalBinDir_\gdal-data
* Run the conversion
* pathToConverters\Option1d.py _PathToInputCDB_ _PathToOutputCDB_
