A
All
right
recording
so
for
today's
meeting,
update
on
the
cdca
home,
where
exactly
we
are
so
here's
the
length
of
the
second
home
presentation.
Let's
start
with
this,
what
do
we
have?
So
this
is
the
concept
of
the
actual.
A
Do
a
slideshow
concept
to
reality.
This
is
as
of
july
2022
we're
working
on
and
finishing
the
inside.
Still
still
still.
This
is
a
2016
build
aquaponics.
First,
first
cdca
home
version,
aquaponics
turned
into
pool
interior
global
village.
Construction
sets
still
setting
out
to
reinvent
collaborative
civilization.
A
Now,
as
far
as
the
cd
go
home,
that's
a
key
thing:
we've
got
housing
is
a
key
need.
So
now
we've
got
the
photovoltaics
on
the
roof.
You
can
actually
download
all
the
assets
now,
so
you
can
click
on
this
house
assembly
file,
it's
both
in
ifc
format
and
free
cad
format.
Yes,
ifc
you've
heard
that
right,
that's
industry,
foundation
classes,
that's
a
simple
export,
you
go
into
freecad
19.
A
A
A
When
we're
doing
the
finished
concrete
work,
we
don't
want
any
bolts
to
be
in
there,
because
we
want
that
to
be
a
super,
easy
job
for
a
power
trowel,
which
is
very
quick
and
effective
floor
plan
of
the
first
floor.
Kitchen
bathroom
stairway
second
floor,
two
bedroom
two
bath.
We
can
also
think
about
dividing
the
upper
floor
into
three
bedrooms.
A
Because
we
thought
oh
well
to
cut
all
those
joists,
those
tapers.
B
A
What
you
see
is
that
the
slant
here
is
actually
makes
for
a
complication
when
we
had
a
slanted
roof,
slanted
joist
set
of
roof
joists
before
so
now,.
B
A
B
A
B
A
B
A
B
The
collaborative
part
goes
follows
from
here:
we've
got
the.
A
Full
model
now
we're
gonna
generate
modular
details
that
can
such
that
we
can
extract
bills
and
materials
readily
from
the
overall
freecad
file.
Okay,
if
you
want
to
look
at
what
this
looks
like
for
the
build,
the
idea
is
still
the
same.
You've
got
human-sized
panels
that
you
put
into
place.
That's
that's
effectively.
The
model
still
stands.
That's
that's
how
we
build
four
by
eight.
In
fact,
it's
actually
four
by
nine,
primarily
as
far
as
the
panels
go.
B
B
B
A
Go
diy,
that's
much
less
expensive,
so
94
000!
If
you
want
to
go
diy
in
the
city
where
land
is
going
to
be
a
little
well
we're
putting
25k
for
land
25
000
diy
in
the
country,
it's
about
68,
69
000.
So
once
again
the
main
thing
is:
there's
a
60
000
material
cost
and
some
other
cost
data.
On
top
of
that,
so
the
various
scenarios
from
turnkey
builds
to.
If
you
build
it
yourself
for
69
000,
this
is
our
utility
channel
design.
Still.
This
stands
basically
wire
raceway
through
all
the
panels.
A
This
is
slightly
controversial,
though
we
should
not
have
problems
going
through
codes
with
this.
We've
got
this
verified
by
code
officials,
so
let's
zoom
out
at
this
one
and
go
into
the
master
files.
So
what
are
we
doing
for
cad
collaboration?
A
A
Well,
let's
take
a
look
at
what
the
actual
file
looks
like,
and
we
have
this
in
a
simple
part
tree
here.
So
if
we
hide
everything
here,
this
is
what
we
get
so
starting
from.
First,
not.
A
B
A
A
A
A
That's
what
all
the
guts
look
like
kitchens
stairs
bathrooms
on
each
floor.
The
bathroom
on
the
first
floor
appears
to
be
missing,
but
that's.
B
The
interior
now
there's
a
numbering
of.
A
B
A
At
the
interior,
the
walls
there
are
their
number
pretty
much
like
one,
two,
three
and
so
forth
to
about
about
30
or
so
interior
modules.
So
each
one
of
these,
like
that's
once
again,
a
four
by
nine
sections,
so
they're
all
numbered.
Now.
How
do
we
store
this
on
the
internet
on
the
wiki?
So
here's
our
own,
all
of
our
master
files,
but
you
go
down
here.
A
The
two
things
we
want
to
do
right
now
is
build
cheat
sheets
and
I'll
show
you
how
to
do
that
so
build
cheat
sheets
for
every
single
module
all
right.
So
where
are
all
the
modules
they're
here
so.
B
B
A
Floor
exterior
so.
A
B
B
B
A
Cheat
sheets
like
oh
here's,
the
one
panel
on
the
interior
wall.
This
is
and,
as
you
can
understand
our
standard
4x9
panel,
this
we
generate
readily
out
of
freecad.
So
in
this
presentation,
I'll
show
you
exactly
how
to
do
that
and
we're
working
in
freecad
16
and
the
idea
here
is
go
through.
So
here
we've
got
all
these.
These
are
interior
walls,
but
for
these
build
cheat
sheets
from
here
I
covered
all
the
interior
walls.
B
A
A
B
A
A
A
B
A
Yeah,
so
this.
A
Check
check
means
that
it's
done
on
the
cheat
sheet
so
anytime.
The
cheat
sheet
is
done.
We
put
a
check,
but
we
want
to
put
these
cheat
sheets
up
in
this
section
here.
A
B
A
A
A
B
A
7
29
22.,
you
go
here
and
you
download
that
just
click
on
that
so
working
file.
A
A
A
B
A
A
B
B
A
A
A
A
A
B
A
B
B
A
A
A
A
A
B
A
Here
we've
got
absolutely
individual
parts
and
this
would
be
good
for
like
now.
You
can
label
all
these
and,
in
the
final,
very,
very
final
file.
You
want.
A
B
B
B
A
A
A
A
A
A
A
A
A
B
A
Of
it
and.
A
B
They
would
be
recognizable
when
you're
generating
building
materials.
B
A
B
A
B
It
so
there
you
go
if
you
use
this
compound
now
you
can
select
this
compound
and
now.
B
A
Forward
face.
A
B
A
A
There
you
go,
you
can
continue.
A
A
B
Far,
so
that's
that's
what
you
do
and
this.
B
B
B
B
B
A
A
A
A
A
A
B
A
A
A
A
B
A
A
A
A
A
A
B
A
A
A
B
A
A
Exercise
and
of
course,
you
can
start
automating
this
with
python
and
freecad.
B
And
so
forth,
so
yeah
here's
a
placeholder
for
exterior
world
too.
So
anyone
who
wants
to
contribute
to
this
please
do
so.
A
The
way
you
know
that
this
is
done
like
here,
I
put
this
check
on
it.
A
A
A
It's
pretty
much
what
you
need
to
to
get
a
person
to
do
exactly
what
you
need
them
to
do
in
a
large
swarm
build
where
we
build
actually
like
48
of
them.
At
the
same
time,
if
you
have
48
people,
each
person
can
take
one
of
the
modules
and
there's.
A
B
A
Radical
time
efficiencies
for
time,
saving
of
how
fast
you
can
build
these
things,
and
you
see
how
kind
of
how
this
modular.
A
Story
first
story
of
the
house
with
a
bunch
of
unskilled
volunteers
or
participants.
In
the
workshop
we
were
able
to
put
up
the
whole
first
floor
in
one
hour
so
that
once
again,
the
the
time
compression.
