This is a problem on GeoGebra 3D appli on iPhone and Web application.

I want to show the section of surface with a slider.

ex.

f(x, y)=x^2+y^2

b=slider(-2, 2)

y=b

Curve(t, b, f(t, b), t, -2, 2)

But, I can not refer the value of slider b for constructing the space curve.

eq1: IntersectPath(p, a) in last command being p the name of plane y=b

be careful y=b is a plane not a line. you must type y=b when the focus is on graphics3D doing click on it
