Even if you’re experienced with using a computer, learning a new software program
presents two problems. The first is learning how to get around the program; the second
is learning how to make the program do what you want it to do. We’re excited about
what SketchUp can do to make woodworking easier and better, and I’ve been working
on developing methods to help folks learn it. I’ve come to realize that instead of
starting at the beginning by making simple models, you can dramatically shorten the
learning curve by starting at the end.
The real value of SketchUp is the amount of information within the model, and the
ease with which you can retrieve it. Even if you never draw a line with SketchUp,
you can better understand projects before you head to the shop. If you start with
an existing model, you can learn how to orbit, zoom and pan without the pressure of
creating something. You can learn how to move components of a project around, get
a better look, and take them apart without the fear of messing something up. The image
above is Roy Underhill’s Tool Chest from our June
2009 issue. It's a good example because some of the joinery is tricky, and
that can be hard to describe with printed words and pictures. But it is easy to understand
if you take it apart and look at it from any angle or distance you want.
To get started, you need to download and install SketchUp on your computer. The software
is free from Google, and information about getting it can be found on the Popular
Woodworking SketchUp Page. There, you can also find most of the models we have
made available (also absolutely free). You’ll find all of our models on our 3D Warehouse
collection, accessible through our SketchUp page. Browse the collection and download
something you’re interested in.
Spend some time just looking at the model from different points of view, using the
Orbit, Zoom and Pan tools. There's a lot of help available within the program, and
one of the best helpers is the Instructor window. You can find it under the Windows
menu in the program; when you have it open, it will show you the basic moves of each
of the available tools. Click on a tool and the Instructor window will tell you how
to use it. When you're able to move around the model without getting lost or
bumping into things, start using the Move tool to take the model apart. In the image
above, I clicked on the top of the chest and moved it vertically. Notice that the
top moves as one piece and the entire top is highlighted in blue.
That lets you know that SketchUp thinks of the top as a single unit – a component.
If you click to highlight it, right click, then select Explode from the pop up menu,
you’ll be able to move the individual parts around. All of the parts of the model
can be found in the Components window. A good SketchUp model is organized this way.
When you draw things in SketchUp you draw lines and connected lines will form faces.
When you have enough lines and faces for something to look like a piece of wood, make
it into a component and it will behave like a piece of wood. Here we have a good look
at how the joints of the frame work with each other and with the panel.
Down at the base of the tool chest we can see what St. Roy was talking about in the
article. Again, all I did was orbit and zoom to the area I wanted to look at. Then,
using the Move tool, I disassembled the base. Putting it back together will give me
a good idea of the sequence of moves to make in the shop when working on the real
thing.
When I was a kid, I learned a lot about how things work by taking them apart. And
unlike the telephone in the kitchen that always sounded tinny after I put it back
together, you can take things apart in SketchUp fearlessly. If you mess things up
you won’t have to run away from home; you can download a fresh version of the model.
And in the process, you’ll learn a lot about the program before you start to draw.
p.s. I’ll be teaching several SketchUp classes, and we’ll have a “drop-in” clinic
available for additional hands-on training, at the Woodworking
in America: Furniture Construction and Design conference, August 14-16 in St.
Charles, Ill. There’s still time to register.
