Truss with regular height, created with VisualARQ beam objects. You should have VisualARQ installed and loaded before opening this definition. It contains VisualARQ beams styles that come with VisualARQ-meters templates, so open that template before launching Grasshopper with that file.
The truss only works with straight curves located on the XY Plane. For leaning straight curves or even curved paths, it may require more development.
This example has been developed to showcase a beam style created from a Grasshopper definition, as you can see in the video below.
