Thank you for your response, but I was not very precise. I know about 
classes, and am using it for other layers, but what I don't know is what 
parameter within the class hierarchy can be used to control the width of 
the line being plotted (I tried size, but all lines still plotted with 
the same thickness). I can use color to differentiate the special lines, 
but is there anyway to make the selected class plot with a selected line 
thickness.

Thank you,

Don

p.s. Happy New Year!
