Designing in SketchUp
In my Principles of Technology class, we’re using Sketchup to design the parts we will make for the Mendocino Motor. Though we’ll fabricate the parts with hand and power tools, you can also use Sketchup to make the files needed to cut parts on a mill, Makerbot, Shopbot or other CNC tools.
The Mendocino Motor project appears in the Teachers’ Pet Projects section on
in MAKE, Volume 20, page 79.
Here are some techniques to design parts for the motor:
First get familiar with the Sketchup interface. This is pretty easy, the software is rather intuitive. A good place to start is by making whole shapes with the rectangle and circle tools. Draw a shape, then use the Push/Pull tool to extrude it up or down. You can make a shape on the side of another shape, then pull it out or push it in. Make some shapes. Mouse over the tool icons and you should see the name of the tool in a popup.
