Look at the picture. I want get the small plane by the polyline on the large plane. How can I should do? Thanks.

Hi
for all the (groups of) locations i want to set boundary conditions or evaluate i create components in the meshing tool - then u can just choose them.

seems that u want to clip the surface in CFX-post -> i would try:
insert location-> iso clip -> the plane in the picture/visible parameters: X>..., X<..., Y>... but u need a new variable (that describes your curve)
