DeconstBrep:Creating and dividing the curved surface to get the centroid on the surface.

Weave:Using the divided surface and weaving the point in order to get the arches to join at the centroid. Pipevariable:Giving the arches it’s thickness.

THE BRIDGE WITH ARCHES

Polygon:Using prepframes and Polygon to give the arches a hexagonal cross-section.

RuledSurface:Using the arches to create and divide its surface.

Webbing:Once the surface is divided, we can connect various points and create the Bridge’s web pattern.

ARCHES WITH WEBS

DivideCurve: Further dividing the curve to create points on the central axis for the designing of the base of suspension cables.

Explode tree:Creating variable points on the central cable to join the intersection of arches, webs and cables.

Apex Surface:Creating a curved culmination of the webbing.

APEX ARCHES AND SUSPENSION CABLES

Weave:Listing all the points on the suspension cable.

Arch Apex:Setting the parametrical data for the consturction of the webbing, apex curves.

Evaluating Curve:Constructing the suspension cables with solid geometry joining the arches and the base.
