Week 1.1 - 2D Basics

Joshua Barbanel Reefs (2014-present)

Touch and Feel with a variety of digital fabrication examples.

Let’s work through Rhino 2d basics together.

Create new file from template. Small objects inches.
User interface:
- Switch between single and quad (four-up) display.
- Pan, tilt, zoom in display.
- Turning Grid Snap on and off. (To create points that stick to origin, 0.25in, etc.) Try as a text command: Type Snap once to turn it on. Once to turn it off.
2D Primitives
- Line.
  - Choose start of line, end of line.
  - Hold shift key while drawing to make the line orthogonal (Right Angle). Ortho
- Rectangle
- Circle
- Polygon
2D Operations
- Trim uses one object to cut and delete parts of another object.
- Split uses one object to cut and split another object.
- Join connects objects to form a single object
- Extend lengthens or shortens a curve
Organization
- Layers. Using layers.
- Group
- Ungroup
- Selecting. How to Select things with the mouse.
- Selection Menu
Transforms
- Scale
- Rotate
- Move
Direct Manipulation
- Changing objects once you have drawn them. We are dealing with NURBS
- PointsOn
  - Click and drag to move points. Use transforms (Move).
- PointsOff
