How to write CST 2D result field to output?

Hi, I need to determine the values ​​of the field on a definite plan in CST, the use of plot data ASCII, does not allow to fix the height, with the limits on a plan (eg Xmin Xmax Ymin Ymax with a Z fixed )
Any information will be appreciated.
Thanks.

You can use template based processing in 0D results. You can output 0D/2D/3D field to an ascii file.
