Recently, I had a class of 7th graders designing in Sketchup. One of the projects is to accurately design a block of 2″ x 2″ x 1.25″. These designs were then converted to G code with Millwizard by an 11th grader who then milled them in the high school across the street on a Taig Micromill. This was a fun project that helped illustrate the concepts and processes of separating the design from the manufacture of objects.

The way it worked out was that the middle schoolers would make some designs, and share them with the high schooler. If the files were designed correctly, proper size, no overhangs, then they would be converted to code and milled. He was able to process 4 files in one class period by cutting in 2 inch insulating foam. Then, the next time I met with the 7th graders, I gave them the blocks they designed.

Flashback: SketchUp 101

By Goli Mohammadi

I'm a word nerd who loves to geek out on how emerging technology affects the lexicon. I was an editor on the first 40 volumes of MAKE, and I love shining light on the incredible makers in our community. In particular, covering art is my passion — after all, art is the first thing most of us ever made. When not fawning over perfect word choices, I can be found on the nearest mountain, looking for untouched powder fields and ideal alpine lakes.

This month’s theme of Make Space for Crafting has got me thinking about designer/hacker/artist Emily Albinski’s helpful 101 feature on SketchUp, Google’s free 3D modeling software, which originally appeared on the pages of CRAFT Volume 09. As Emily writes in her intro: For decades, computer-aided design (CAD) applications were expensive tools used only by a […]

Sketchup is an easy-to-learn program for 3D modeling. While it gives you an easy way to design creatively, it is a bit more challening to design accurately. If you are going to make physical models of your designs, you will need to make them small enough to fit on the tool that will make the part. You can send the 3D models to a number of toos, including the ShopBot, CNC Mill and MakerBot, among others.

If you follow these pretty easy steps, you can get yourself and your students into the habit of designing accurately dimensioned objects. Here is a set of screenshots and a sample file that show the steps of this process.

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.

Dan Smithwick is working on developing a system so that people can design houses, buildings and other structures in Sketchup, then have the parts cut on a Shopbot, which can then be put together with a few more tools than a rubber mallet. Dan has been working with MIT Professor Larry Sass. Take a look […]

Asteronimo writes about SliceModeler for Sketchup: Based on TIG‘s Slicer script I wrote a plugin that slices a solid 3d model along 2 axes, f.i. an X- and a Z-axis. You can enter separate parameters for each axis. After the slices have been created it calculates the slots for each intersection which allow the cross […]
