Parabola problem

[glassmaker]

I am trying to create a parabolic datum curve using the from equation option. I'm not having any success. The equation of the parabola is X=(y^2)/(4*F) with the focal point at 1490. Can anyone help? Unfortunately, There is not much documentation on how to use this functionality.

Not sure if this is what you need, but it might help:

F= 1490
s= 1490*t

x = (s^2)/(4*F)
y = s
z = 0
