Representation | Rhino Intro II

2A / 5 A short diary of five introductory software sessions, covering Rhino (two parts), ArcGIS, 3D Scanning and Adobe After Effects. Delivered via The University of Greenwich as part of the Landscape Representation module within the Master of Landscape Architecture program.

The Task

1 hour practical workshop spent building a train station, in order to be able to explore VRay for Rhino (B) and Grasshopper (C) software. The individual build components comprised of rail tracks and sleepers, an elevated platform on concrete legs, glass roof and framework plus indoor bar.

5 New Commands I Didn’t Know Yesterday

  1. Array| an excellent shortcut that will save me a lot of time Cut and Pasting! Allows you to quickly duplicate an object in any direction and preview a draft version in pink. See example: rails duplicated on y-axis, where x = 1, y = 150, distance = 0.75m, z = 1. 
  2. ExtractWireframe | Useful new trick to quickly duplicate a wireframe onto a new layer to build skeletal forms or frameworks. See example: wireframe of the roof. 
  3. OffsetSrf | Using this wireframe layer, we next applied ExtrudeCrv then OffsetSrf to create a 3D framework. See example: creating a solid ‘space frame’ to support the roof. 
  4. Fillet | I’d used this before but never really understood it. Now I can clearly see the benefit of creating a clean curve from two straight lines. See example: base of train platforms.
  5. Sweep1 | Interesting command although I haven’t fully grasped how I would use it, as there doesn’t feel to be enough control. Sweep1 connects one rail curve with one cross section curve; Sweep2 connects 2 rail curves. See example: mushroom-like form of the station bar.
