Question: a 2D plot from a 3D plot

Dear Friends

I want to know that how can I plot a 2D curve in 3D? 

I need to plot the curve for example z=y^2, in a 3D space and exactly in the plane x=0. The ranges are -1<y<1, -1<x<1, 0<z<1

(I want to copy and paste this curve in another 3D figure.) 

Thanks a lot
