Representation | Rhino Intro I

1 / 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

3 hour practical workshop, creating 3D shapes in Rhino. The final output was to build a pier, lighthouse, terrain, path and contours, that could be further modelled in Rhino as well as taken into Adobe Illustrator for digital enhancement.

Key Basic Commands Used

Creating 2D and 3D shapes: Polyline, Spline, Extrude, Circle, Pipe, PlanarSrf

Progressing from individual objects: Split, Join, Rotate

Shortcuts to save time: Copy, Paste, Move, Offset (ThroughPoint)

Developing digital images: Make2D

5 New Commands I Didn’t Know Yesterday

  1. Loft | Really easy way to fill a space between two joined curves to create a surface. Previously I’d been doing this manually with the 4-point surface command button. See example: base to the top of the lighthouse.
  2. Project Curve | Quick command used to draw a shape on one plane and then accurately project it onto another existing object, particularly useful when that object has curved sides. See example: the path which was drawn on C Plane then projected onto the varied terrain.
  3. ExtractSrf | I didn’t realise the strange geometric effect I often created was an error sign showing that two surfaces were meeting, and wouldn’t be accepted by a 3D printer. Extract Surface is a useful command to quickly delete specific sides. I had been using the Explode command previously, which creates extra work. See example: removal of the base at the lighthouse door.  
  4. Rebuild | A flat ground plane for the terrain was created with a 4 point surface. Rebuild command (with points visible) provides a default grid of an extra 10×10 points to manipulate. See example: dark green terrain with rolling hills.
  5. Project (a mode not a command) | Hadn’t been aware of this useful option (checkbox) to assure that you are always drawing all points on the C Plane. Switch off, and then work again in perspective to move the correct shape to the required location.
