7. Make Your Robot's Mouth
Start by making a mouthpiece with a box
that's smaller than the robot's head.
To create the speaker-grill ridges, make a ser-
ies of even smaller hole boxes. You can make
one and create copies by clicking the Copy
button; using copy-paste keyboard com-
mands; or clicking on the original, holding
the Option key, and dragging off a clone.
Space them evenly apart and slide them into
the mouth box (
Figure 4-8
).
Figure 4-6.
Select the topmost vertical dot
Then, with only the hole boxes and the
mouth box selected, click Group. This will
apply the hole objects to the box, cutting out
the negative shapes, and turning them into
holes (
Figure 4-9
).
Figure 4-7.
Select the hole box and use the arrow
handle to move it down 2 mm
Select the hole box and the head box again,
and align them on the horizontal plane (but
again, don't click the vertical align buttons
or else the hole box will move to the top or
bottom of the head box).
Select all the pieces and combine them into
a single object by clicking the Group icon.
You now have a nice 2 mm border on the top
and sides of your hollow robot head.
By default, the workspace has a
grid snap size of 1 mm, so when
adjusting the space between two
objects, you can use the arrow keys
to move the selected shape in 1 mm
increments.
