Two designs, in Rhino, to be laser cut (keep it under 24″ x 18″)

• Algorithmic: Start with a basic shape, repeat a process systematically (e.g. the repeated diminution exercise in class).  Make the necessary adjustments in the model to allow it to be laser cut.
• Based on the real world: take a top-down (bird’s eye) perspective photograph of a real-world object, import the image into “Top” transport of rhino, and model it with lines and curves; make the necessary adjustments in the model to allow it to be laser cut.
• In both exercises, consider what material you would use and why.
• Upload both models to Black board before Monday morning’s class.

COMPANY

• McNeel: The company that makes Rhino3D
• Rhino3D: The main website
• Rhino3D Tutorials: The official documentation

COMMUNITY

• The Rhino3d wiki: community developed site with all things Rhino
• Rhino3d newsgroup: people asking/answering questions

NB 1.  When there’s a length or an option, you can type it (if you can)
NB 2.  Use a two button mouse, use a big/second screen (if you can)

drawing: (you can either click to draw or type the dimensions you want)

• points
• circle
• line
• rec
• polyline
• curve

measurements:

• length: length of line or curve
• distance: distance between two points
• area: area of a surface

geometric transformation:

• orient: good when the thing you’re moving is asymmetric/sided/chiral
• offset: scale and copy
• scale1D: good for resizing lines
• scale2D: good for resizing flat shapes
• scale (you can indicate with numbers the scaling factor)
• move
• copy
• arraycrv: orient and copy

2d-3d-2d:

• loft: make connecting surface between two lines/curves
• extrude
• make2d: create 2d shape of selected surface, according to current view
• unrollSrf: turn a volume into flat components
• dupBorders: produce curve from boundary of a surface

cutting/expanding:

• explode
• split: divides a line/curve/surface at a center point/line/intersective-surf/curv
• trim: split + delete
• extend
• rebuild

make many out of one:

• divide: dividing lines/curves into equal parts
• rebuild: either turn cuves into lines or make ugly curves pretty curves

housekeeping/getting-around:

• layer: show layers window (use many layers!)
• show/hide
• setPt
• zs: zoom set, show you just the selected object in the active transport
• join: make one curve out of many segements
• group
