The 3 attached files demonstrate using Marionette to generate a roof truss from a guide curve.  - Truss Network.vwx : This file contains a network that uses a named curve and some dimensional input parameters to produce truss geometry as extrudes on the layer plane. - Truss Node.vwx : This file wraps the truss network from the first file and uses it within another network. This network takes a freeform NURBS surface, slices it into a series of curves using the contour node, and generates a t
