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
