Using NURBS Curves or Polylines as Beam Elements.

Karamba recognises a line input in the Line to Beam component as a straight line connecting a start and end point. When you have NURBS curves (that have more than 2 control points and a curve degree higher than 1) referenced from Rhino or a grasshopper definition, these must first be discretized into line elements. This can be done easily using the Rebuild command or component to convert the curve into a polyline. Make sure to explode the polyline into separate line elements before plugging it into a Line to Beam component.
