`Loft`

A loft operator.

Example

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

    -- Create two lines to loft between

line1 = project.Contents.Geometry:AddLine(cf.Point(1, -1, 0), cf.Point(1, 0, 0))
line2 = project.Contents.Geometry:AddLine(cf.Point(0, 0, 0), cf.Point(0, 0, 0.5))

    -- Create the loft between the two lines

project.Contents.Geometry:Loft(line1, line2)
