Can one put in an equation into Inventor and the program generate a spline from this equation?

The equation could look something like the following. (This is a simple equation for a simple helix)

radius = 100

lead = 50

theta =2*pi*u

zeta = lead*u

x = radius*cos(theta)

y = radius*sin(theta)

z = zeta

Range from 0 to 1
