Building a Bed |
Caleb Hsu |
Objective: Build a bed with adjustable length and leg height.
Start by making the mattress. We can add parameters after we have determined our dimensions.
<craft>
<cube size="40 75 7" color="teal"></cube>
</craft>
Next, make the base of the bed frame.
<craft>
<cube size="42 77 5" color="brown"></cube>
</craft>
Create a headboard <part> by lining up two supports and a headboard in a <row>. To make the rounded headboard, <stack> a scaled <cylinder> over the row.
<craft>
<part name="headboard">
<stack spacing="-27">
<stack spacing="-22">
<cylinder radius="20" height="4" transform="
rotateX(90)
scale(1,1,0.7)
"></cylinder>
<cube size="38 4 30"></cube>
</stack>
<row spacing="38">
<repeat n="2">
<cube size="2 4 36"></cube>
</repeat>
</row>
</stack>
</part>
<headboard></headboard>
</craft>
With the dimensions of the frame in mind, make the front legs for the frame by lining two sized <cubes> in a <row>.
<craft>
<row spacing="36">
<cube size="3 3 8"></cube>
<cube size="3 3 8"></cube>
</row>
</craft>
Create a pillow <part> by scaling a <cylinder> so it becomes more flat.
<craft>
<part name="pillow">
<cylinder radius="10" height="26" color="white" transform="
rotateY(90)
scale(1,1,0.4)
"></cylinder>
</part>
<pillow></pillow>
</craft>
Now <stack> the mattress and frame base together, centering and aligning with the pillow using <g>. At this point, we can name the lower cube "base" using the class attribute for future stacking purposes.
<craft>
<part name="pillow">
<cylinder radius="10" height="26" color="white" transform="
rotateY(90)
scale(1,1,0.4)
"></cylinder>
</part>
<g layout="centerX() alignY(5%) lineupZ()">
<stack>
<cube size="40 75 7" color="teal"/>
<cube size="42 77 5" class="base" color="brown"/>
</stack>
<pillow></pillow>
</g>
</craft>
Center and align the headboard using <g>.
<craft>
<part name="pillow">
<cylinder radius="10" height="26" color="white" transform="
rotateY(90)
scale(1,1,0.4)
"></cylinder>
</part>
<part name="headboard">
<stack spacing="-27">
<stack spacing="-22">
<cylinder radius="20" height="4" transform="
rotateX(90)
scale(1,1,0.7)
"></cylinder>
<cube size="38 4 30"></cube>
</stack>
<row spacing="38">
<repeat n="2">
<cube size="2 4 36"></cube>
</repeat>
</row>
</stack>
</part>
<g layout="centerX() alignY(0%)">
<g layout="centerX() alignY(5%) lineupZ()">
<stack>
<cube size="40 75 7" color="teal"/>
<cube size="42 77 5" class="base" color="brown"/>
</stack>
<pillow></pillow>
</g>
<headboard transform="translate(0,0,-8)"></headboard>
</g>
</craft>
Stack the assembled bed over the front legs, using the at and layout attributes.
<craft name="bed">
<part name="pillow">
<cylinder radius="10" height="26" color="white" transform="
rotateY(90)
scale(1,1,0.4)
"></cylinder>
</part>
<part name="headboard">
<stack spacing="-27" color="brown">
<stack spacing="-22">
<cylinder radius="20" height="4"
transform="rotateX(90)
scale(1,1,0.7)
"></cylinder>
<cube size="38 4 30"></cube>
</stack>
<row spacing="38">
<repeat n="2">
<cube size="2 4 36"></cube>
</repeat>
</row>
</stack>
</part>
<stack spacing="-8" layout="alignY(100%)">
<g layout="centerX() alignY(0%)">
<g layout="centerX() alignY(5%) lineupZ()">
<stack>
<cube size="40 75 7" color="teal"/>
<cube size="42 77 5" class="base" color="brown"/>
</stack>
<pillow></pillow>
</g>
<headboard transform="translate(0,0,-8)"></headboard>
</g>
<row spacing="36">
<cube size="3 3 8"></cube>
<cube size="3 3 8"></cube>
</row>
</stack>
</craft>
Now that we've finalized the dimensions, parameterize length and leg height.
<craft name="bed">
<parameter name="length" type="int" default="75"/>
<parameter name="legHeight" type="int" default="8"/>
<style>
.base { color: brown; }
.mattress { color: teal; }
.legs { color: brown; }
headboard { color: brown; }
pillow { color: white; }
</style>
<part name="headboard">
<stack spacing="-27">
<stack spacing="-22">
<cylinder radius="20" height="4" t="
rotateX(90)
scale(1,1,0.7)
"/>
<cube size="38 4 30"/>
</stack>
<row spacing="38">
<repeat n="2">
<cube size="2 4 {{(legHeight * 2 + 20)}}"/>
</repeat>
</row>
</stack>
</part>
<part name="pillow">
<cylinder radius="10" height="26" t="
rotateY(90)
scale(1,1,0.4)
"/>
</part>
<stack spacing="{{-legHeight}}" l="alignY(100%)">
<g l="centerX() alignY(0%)">
<headboard t="translate({{0,0,-legHeight}})"/>
<stack l="alignY(5%)">
<pillow></pillow>
<stack>
<cube size="40 {{length}} 7" class="mattress"/>
<cube size="42 {{length + 2}} 5" class="base"/>
</stack>
</stack>
</g>
<row spacing="36" class="legs">
<cube size="3 3 {{legHeight}}"></cube>
<cube size="3 3 {{legHeight}}"></cube>
</row>
</stack>
</craft>
