Import .dat file using Python import function to load airfoil

Dear all,

i have a question regarding the import function with Python scripting.
I want to import an airfoil.dat file which basically are coordination's to create a wing profile in Abaqus.
I'm currently converting the .dat file into a .dxf file to import the coordinates in Abaqus.
The problem however is that Abaqus imports the coordinates and adds a line on the x-axis. this means that i have a solid plate through my wing when i extrude the sketch.
I can't delete the plate because my script has to work with different kinds of airfoil.dat files which have different coordinates... 

Is there anyone who knows how to import the airfoil.dat file directly into Abaqus ???

Kind regards,
Dylan Hoogsteen.
