Going 3D with Blender: Modeling a chest
In this article we model a chest with Blender.
Modeling a chest
Look at the image above and you see the chest we are going
to create. For that we open the stage environment that we built
in my first article about Blender. If you haven't read the
article and built the stage environment yourself you should
have a look at Going 3D with Blender:
Very first steps first before you proceed with this
article. With this stage environment we have kind of a default
setting with lights where we can place the chest in.
By the way the current version of Blender as of this writing
is now 2.31a. The interface of Blender has changed a lot but
after working with it for a little while you will find that the
changes are really for good. Congratulations and thanks to the
Blender team for their excellent job! :)
If you look at the chest you can easily see that the two
main shapes are simply a box and a cylinder that is cut in
half. The difficulty lies in giving it the impression of
thickness. The method I will describe heavily uses extrusion.
If you have any other suggestions on how to model the chest let
The chest box
For the box add a grid with xres=12 and yres=8
(Space-->Add-->Mesh-->Grid with xres=12 and yres=8) in
top view (in layer 2). In the second inside rectangle select
the single lines and move them out close to the outer
rectangle: Start with the second line from the left and select
it. Next press g and then move it with the arrow key to the
left. Do the same with the other three second lines of the
Now select everything (press a twice) and in front view
extrude a bit (press e, enter, arrow key, enter) so that you
get a board.
In top view select the two outer rectangles (deselect the
points inside by pressing b and the right mouse button)and in
front view extrude them and move them up (press e, enter, arrow
A simple model of the box is ready.
Select the top line in front view (if it isn't selected
anylonger) and extrude a bit (a bit more than the distance
between the two lines on the bottom), then press e again and
extrude again a bit (as much as the distance at the
Assign the whole box a pink colour (go to the material
buttons, press "add new" and move the colour sliders to
R=1,G=0,B=1), then select the inside of the box (that's
everything except the four lines on the corners in top view and
the bottom line in front view) and assign a light pink colour
(in the edit buttons press "New", "Select", then go to the
material buttons, press "add new" and move the colour sliders
to R=1,G=0.6,B=1, go back to the edit buttons and press
Now select all points (press a twice), then deselect (press b
and the right mouse button) the inner points in top, side and
front view each (see figure below).
Assign a yellow colour (in the edit buttons press "New",
"Select", then go to the material buttons, press "add new" and
move the colour sliders to R=1,G=0.1,B=0, go back to the edit
buttons and press "Assign").
In top view extrude and scale up (press e, enter, s, arrow
Assign the yellow colour again (simply press "Assign"
The box is ready.
On the two smaller sides we will add some handles: In front
view hit Space, Add-->Mesh-->UV Sphere with the Segments
and Rings at 32 (which usually is the default value), scale it
down (press s) and flatten the sphere a bit (press s and by
holding the middle mouse button down restrain the scaling down
to the thickness). Move it so that it is on the corner of the
side in front view and in the middle of the box in side view.
Go to the edit buttons and press smooth, give it a light pink
colour (R=1,G=0.6, B=1). Copy it (shift + d) and move (press g)
it to the other side.
For the ring add a mesh circle (hit Space,
Add-->Mesh-->Circle (Vertices=32)) in side view, then
scale it down, then in side view (in edit mode) press e and
then s and scale it up for the right thickness. Select all
points (press a twice) and now extrude (press e) and scale
(press e) in front view. Give it a colour. In the edit buttons
menu press "Set Smooth". Then copy it (shift + d) and move
(press g) it to the other side.
In side view copy (shift +d) the squeezed sphere, scale it
down (press s). Then in front view move it out of the big
sphere to make it visible. Copy it (shift +d) and move (press
g) it to the other side.
For the lid add a cylinder (hit Space,
-->Add-->Mesh-->Cylinder, let the vertices have a
value of 32) in top view (in the third layer). Press a to
deselect all points, then press b and mark the bottom half.
Next press x and delete the vertices.
Press a to select all points, then still in top view press e
(to extrude), enter and s to scale everything a bit down.
Now press g and move the inner half-cylinder a bit down so
that its bottom line is exactly on the bottom line of the outer
Leave the inner half-cylinder still selected. Give the "two"
half-cylinders a pink colour (go to the material/shading
buttons, press "add new" and move the colour sliders to R=1,
G=0, B=1). Now go to the edit buttons and assign a new colour
to the inside of the lid as it should be of a lighter pink
colour: Press "New", "Select", then go to the material buttons
and assign the new light pink colour with "Add new", then
colour sliders to R=1, G=0.6, B=1, then back to the edit
buttons and press "Assign". Now make a render (F12) to see if
everything is correct.
A simple model of our lid is ready now.
The upper edge of the lid should be yellow. So in top view
select the bottom line (press a to deselect all points, then b
and mark the line) and assign a yellow colour: like before go
to the editing buttons, press "New", "select", go to the
material buttons, press "Add new" and move the colour sliders
to R=1, G=1, B=0, then go back to the editing buttons and press
Now for the thickness of the rectangle of the lid:
Select the bottom line in top view (press b and mark the line)
if it isn't still selected.
In top view press e, enter, arrow key to move the points a bit
down, enter. Still in top view select the two outer points on
the two sides plus all inner points in the middle of the
rectangle, then in front view deselect the two inner points in
the middle (see figure below).
In top view press e ,enter, s, arrow key, enter (to scale up
to the sides) and the thickness of the rectangle is ready.
Now for the thickness of the arcs:
In side view select the outer arc on bottom and top, then
press "subdivide" (you find the button in the edit buttons
under "Mesh tools", next to "Beauty" and "Fractal
As we need the thickness on both sides we need to subdivide
again: in side view deselect (press b and mark with the mouse,
then right mouse click) the top line of the arc and press
In side view deselect the top and bottom lines that are
selected, press g and arrow key to move the arc line downwards,
then press enter to finish the operation.
Now select the arc points that we obtained through our first
subdivision, press g and arrow key to move this arc line
upwards, then enter.
In side view on top select the first and third line (see
figure below, don't select the point that belongs to the
In top view deselect the inner circle and inner points.
In top view press e,enter, s, arrow key (to scale the arc up),
enter. In the edit buttons press "Assign" to assign the yellow
Now the other side:
In side view select the first and third line on the bottom. In
top view deselect the inner circles and inner points. Still in
top view press e, enter, s, arrow key (to scale the arc up) and
enter when you have exactly reached the other arc points. In
the edit buttons press "Assign" to assign the yellow
The lid is ready!
Putting box and lid together
The lid is in layer 3 and the box in layer 2. Make both
layers visible, turn the lid 90 degrees, then move the two over
each other and scale them. That's it.
Have fun and happy blending! :)
