# Software – Spacegass

Below is a model of the Afton St Pedestrian Bridge located in Essondon in Victoria. The model is a 2D only model and uses cable type members. Below are a series of images showing the progression of modelling a core system of a high-rise building. The project was done under the assumption that the vertical… Read More Software – Spacegass

# CAD – Parametric Design with Rhino and Grasshopper

The below are examples produced from a grasshopper webinar. Basic Parametric Geometry Example Using two curved lines as the boundaries, we divide the curved lines into equally spaced segments. We then define a curved line bridging the two boundary lines originating and terminating at the boundary segments. The height of the arch is controlled by a… Read More CAD – Parametric Design with Rhino and Grasshopper
