The vast majority of technical drawings these days are not done by hand, but rather are done by CAD
software (Computer Assisted Drawing). One CAD program that is free and relatively easy to use is
Google SketchUp. Knowing how to do technical drawing by hand is important in order to be able to
understand how to draw using a computer, just like how you have to know your multiplication tables
before you can understand how to use a calculator well.
Your first task is to install Google SketchUp and watch the first four tutorials. First go to the section on
the Instruction Page below called “Installing Google SketchUp” and follow the instructions. The go to the
tutorial link below. Watch the first four tutorials.
Part 1 - Concepts (3:08)
Part 2 - Drawing Shapes (6:09)
Part 3 - Modify Tools (4:43)
Part 4 - Create a Chair (8:43)
Now create a model of the chair created in the
tutorials, just like you were instructed to in the
Next, use Google SketchUp to create a 3D version
of the orange object to the right.
Note: Be sure to save both your chair, and your
block for task 1! For instructions on how to save,
read the Saving Your Drawing section on the
Instruction Page below.
Next you will watch 9 more tutorial
videos on the same tutorial link as above.

Push Pull (3:33)
Next, use Google SketchUp to create a 3D version of the blue object above. Paint your object a glass
color so that it is transparent.
Next you will watch 6 more tutorial
videos on the same tutorial link as
Tape Measure (3:06)
Text & 3D Text (5:05)
Use Google SketchUp to create a 3D
version of the green object to the
right, and paint it a transparent
color so that you can see the hidden lines. Be sure to label all of the dimensions.
Use Google SketchUp to create a 3D version of any object. The more detail you show, the better. As
always, be sure to label all of the dimensions. The following tutorials are not mandatory, but may help
you with aspects of your drawing.

Go to http://sketchup.google.com/download/gsu.html and click “Agree and Download”
Once it is finished downloading, run “GoogleSketchUpWEN.exe” to run it.
A bar may pop up near the top of your screen. If so, click on it and keep clicking “download”,
“agree”, and “run” until the software is installed.
When it asks you for a template, scroll down to the very bottom of the screen and choose
“Beginning Training Template – Meters”
Click “Start SketchUp”.
The first thing you should do is get a more useful toolbar. Click on the “View” menu, then
“Toolbars”, then turn on the “Large Toolset”. Go into that same menu again, and turn off the
“Getting Started” toolbar.
Under the File Menu, select Save, and choose which directory you want to save the file in. Save
it in your Science folder in My Documents.
To hand in your assignment, attach the file as your normally would in an e-mail. It will have a
.skb extension on the end of the filename.
If you want to use your drawing as an image (say, for your science fair poster board) you need to
Under the File Menu, select Export, and choose 2D Graphic. Choose which directory you want to
save the file in. Save it in your Science folder in My Documents.
This will convert the file to an image in .png format, which can be used by most word processors
and graphics programs.
