CST- Microwave Studio: Export 1D Result For Each Parametric Sweep Automatically

I have to study the parametric variation of three variables (a,b and c) of antenna. Total parametric results i am having is 125. Its a daunting task to export 1D results of each parametric variation manually. If it is possible to export after each parametric sweep variation to the file named "a_b_c.txt" automatically. Then it will be of great help.
Thank you.

Finished by manually exporting each sweeps. Thanks.

Good that you managed it as manually it always works though it is tedious and time consuming but you can use macros to do such tasks.
