Hi,  
I have a data file showing the x and y coordinates of the points with a connectivity list followed. The data is in .tec format and in the header I have,  
VARIABLES = “X”,“Y”  
ZONE N = 52, E=51, F=FEPOINT, **ET=**  
coordinates as x and y here  
connectivity list here.

My question is that I do not know what should I write as the value for **ET**. I tried several options but I the best I got was the points themselves and the connecting lines were not plotted.  
Do you have any suggestions for plotting the data correctly?

Thanks
