Blender 3D
Why are 3D drawing tools a big deal?
Computer Aided Drafting (CAD) is an
important tool for architects and
industrial designers. It enables them
to visualize a solution more quickly
and deeply than if they build a
physical model or work from 2D
elevations and plan drawings.
3D models enable scientists to better
understand and compare complex,
abstract phenomena

Why are 3D drawing tools a big deal?
3D simulators enable pilots and
other professionals to learn skills
quickly, safely and at relatively low
cost.
3D drawing tools will be essential for
animators and game designers of the
future.

Why are 3D drawing tools a big deal?
3D modeling can be used to arrange
furniture or inventory quickly.
In cases where space is critical, such as
circuit board or chip design,
mathematical algorithms are the most
reliable way to optimize layout.
In cases where space layout is based on
esthetics or where the math algorithms
do not exist, 3D modeling can be very
useful.

What You’ll See First
Press “P” to Play
Press “P” to
launch the game
engine.
HOLD “UP” to
launch the
rocket!!! Just a
simple sample.
Press Ecs to exit game
Next we’ll navigate through
different views.
The reason that the rocket is
white is because there is a
texture on it, so the texture
will only show in the game
engine since the mode is set
to textured…this will be better
explained next lesson.

Change View
Select view and select side, front,
or top view.
If you have a number pad you can
press 1,3, or 7 if “Num Lock” is
on.
This is useful for editing objects
symmetrically. This is important if
your trying to make something
look realistic. If the view is placed
by eyeballing…objects made are
likely going to be lop-sided.

Add an Object
Press the space bar over the 3D work
area, or select add from the top drop
down menus.
Select mesh, and choose Icosphere.
You can add anything that is listed,
but for the purpose of this lesson,
add a sphere.

Side View
•Go to Side View or press NO. Pad 3. Now you are at
the side view.
•Press NO. Pad 5 to toggle perspective. Try it to see
what this does. Alternatively, go to the view menu
and select orthographic or perspective view.
Left click and hold over the green arrow.
Move the mouse left and right to move
an object on the x-axis. Try with y and z
also.
Add to the Rocket
Now that you moved the sphere, switch views and move the sphere until the sphere is
in place to be a glass bubble for a pilot to look out of while driving!

Smooth out the Glass
Select editing. F9 is the keyboard shortcut.
Build-It-Yourself.com
Smooth Glass
LEFT Click “Set Smooth” while the
sphere is selected (right click to
select an object)
Use this to have smooth
shading on objects.

Frame For Glass
•Go to front view (NO. Pad 1) and add a mesh circle. Make sure to select
“FILL” option.
•Go into edit mode by pressing tab or select it from the menu.
•Feel free to look at the top view then return to front view.

Extrude Surface
•By pressing “A” you can select and deselect the vertices. These are all the
yellow dots or points where the edges meet. Make sure all vertices are
selected (they will be yellow)
•While in front view, press “E” to extrude, or pull out, the surfaces. Select
region and then move your mouse up a little and left click to anchor this
portion of the object.

Return to Object Mode
•Press tab to go back into object mode.
•Go to the side view.
•Make sure the circle is still selected (highlighted pink)
•Press “R” to rotate…
•Type in 90 (on the numberpad or eyeball it by rotating the mouse) after
pressing “R” and the frame will rotate 90 degrees.
•Now switch views until you get the frame with the window. Rotate
accordingly.

Add Materials
Add materials as we did last
lesson. Here is a quick
reminder for navigation to
add a material. Add Colors
and play with the shading
type.
I will show you how to add
textures and attach the glass
and frame to the rocket next
lesson.

Start from Scratch
For the remainder of this hour, start you own original Blender project after saving the
rocket file. Add an object and edit it. Practice navigation and let’s see what you
create!
Here is a sample of the game logic. Similar to scratch
in how simple but effective it is. With the rocket hull
selected, you can add logic to the selected
object(s)…another lesson though ;P
