hi  
i am working with 2d files. i want to get the graph of different parameters like elevation velocity and pressure at a desired section. so i used the function “plot over line” but in return i got no graph. when i look to the spreadsheet view of “plot over line” there is Nan value for all pramters. Can you help mw with this.
