# SphericalDescription

The description of an analytical curve using the spherical coordinate system.

## Example

application = cf.Application.GetInstance()
project = application:NewProject()

-- Define three local variables used to create a spherical analytical curve

R = "t*sqrt(1+t^2)"
theta = "90"
phi = "deg(arctan(t))"

analyticalCurve = project.Contents.Geometry:AddAnalyticalCurveSpherical(0, 1, R, theta, phi)

-- Access the spherical description

analyticalCurve.SphericalDescription.R = "10*t*sqrt(1+t^2)"
analyticalCurve.SphericalDescription.Theta = 80
