We
did
because
you
don't
have
any
existing
at
the
moment,
so
we
just
made
the
format
which
is
open
enough,
so
you
can
add
stuff
later,
for
example,
right
now,
I
use
actual
properties,
but
the
fan
guys
use
resistance
properties,
but
later
on,
you
could
imagine
anything
more
to
add.
For
example,
I
don't
know
electronic
properties,
some.
B
A
B
At
the
moment,
what
that
is
here
is
just
align
all
the
components
put
some
text
to
describe
them
and
the
kids.
Then
these
screws
are
pretty
simple,
because
we
don't
want
much
detail
in
this
and
the
tits
after
that,
once
all
those
components
are
made
they're
just
copied
here
into
the
final
position,
just
with
with
the
with
using
this
clone
tool,
which
creators
creates
a
basic
link
copy
of
an
object.
So,
for
example,
this
here
is
a
clone
of
this
one
right
here
and
change
the
length
of
this
one.
C
B
A
Tell
me
about
this
one,
one,
practical
application:
if
you
have
the
library
of
parts
in
that
same
drug,
so
you
basically
drew
the
parts
in
one
part
of
the
drawing
in
another.
You
put
the
assembly,
which
is
a
nice
way
to
go.
Can
you
simply
drag
and
drop
and
basically
pick
from
your
parts
to
make
the
panel?
And
how
do
you
do
that
at.
C
B
I
have
this
final
part
here,
probably
I
will
just
export
it
as
a
single
file
and
that
that
you
can
import
in
another
file.
At
the
moment
you
can,
you
have
to
do.
Matt.
That's
manually,
like
I,
could
import
this
whole
file
in
another
file,
but
then
all
the
objects,
including
the
text
and
such
will
come
and.
C
B
C
B
B
B
C
C
B
B
C
C
C
A
Okay,
very
nice.
So
what
what
other
details
do
you
want
to
show
me
there?
So
you've
got
the
assembly.
Let's
see
what
I
should
do
is
I
should
probably
take
a
look
at
my
file,
and
maybe
you
can
walk
me
through
how
I
access
all
these
pieces
just
to
navigate
so
I.
So
in
this
you've
got
three
elements:
one
is
the
parts
break
down
to
is
the
part
the
labeled
assembly
and
three
is
the
assembly
itself.
A
B
C
C
C
A
B
C
B
A
B
A
C
C
B
For
people
to
test
and
then,
if
it's
if
it
working
okay,
you
would
merge
the
branch
into
the
domain
code,
but
in
free
cat.
Since
we
have
long
history
of
being
only
the
three
of
us
and
we
pretty
much
trust
each
other
a
lot.
So
for
those
month
things
we
don't
create
a
branch,
for
example,
if
I
would
fix
a
little
bug
here,
I
would
directly
commit
in
the
after
brunch,
okay.
C
B
C
B
C
B
C
C
B
B
A
C
C
C
C
B
C
B
A
A
A
B
Design
architecture
from
scratch,
you
you
you
prefer
to
play
with
with
undefined
forms
and
not
start
from
components.
You
would
first
design
your
general
shape.
Then
you
would
fit
your
component
in
those
shapes.
So
normally
you
would
probably
want
to
use
a
more
freeform
way,
such
as
blender
on
sketchup,
or
something
like
that
here.
The
exercise
was
a
the
opposite.
Like
start
with
very
defined
components,
and
then
the
general
form
of
the
of
the
windows
will
come
from
those
components
and
yeah.
B
B
B
C
B
A
C
B
B
A
C
C
A
C
A
C
A
A
B
You
could
use
that
for
the
prizes
will,
like
you,
estimate
the
price
of
each
each
component
and
have
some
anyway.
There
are
many
many
uses
for
that
spreadsheet.
Actually,
at
the
moment,
it's
just
too
generic
spreadsheets
like
it
doesn't
have
much
more
purpose,
but
the
ID
in
the
future
is
to
be
able
to
use
that
as
basically
to
collect
the
author
from
your
modern
inner
inner
in
a
spreadsheet
form.
C
C
A
Are
you
going
to
plan
on
doing
the
two-dimensional
picture
and
then
start
looking
at
the
wall,
module
and
then
interface
between
them
I
mean
you
can
also
start
with
interface
between
these
roof
panels
too?
How
do
you
put
them
together
in
detail,
but
you
can
do
just
the
basically
next
to
each
other
part
beyond
that
you
can't
do
anything
more,
but
for
the
next
to
each
other
part
I.
A
B
C
B
C
B
B
A
Because
the
consideration
is
for
various
reasons,
including
the
the
concept
of
parallel
build,
you
would
like
to
get
as
much
work
done
on
the
ground
as
possible,
one
because
it's
easier
and
to
you
can
parallel
that
more
there's
more
people
can
fit
on
the
ground,
then
so
as
much.
The
design
requirement
would
be
to
do
as
much
as
possible,
so
that
design
it
that
we
can
only
do
minor
things
up
when
we're
up
there,
but
do
most
of
it
on
the
ground.
In
a
comfortable
environment,
yeah.
C
C
B
C
B
C
C
A
D
C
B
C
C
C
A
B
A
A
B
D
C
C
A
B
C
A
Can
but
a
key
it
doesn't
scale
for
for
manual
handle
ability.
This
is
heavy
enough
that
two
people,
or
it's
some
reasons
of
cost.
Let's
see
the
reasons
are
one
is
the
weight
of
the
module
and
I
think
there
was
also
a
a
cost
reason
to
the
the
wood
does
not
scale
like
that
in
terms
of
cost
it's
more
expensive
to
go
with
the
double
the
size
as
well.
C
B
A
Yeah,
so
for
greenhouse
applications
that
we
enable
the
hanging
of
a
top
layer
of
growing
from
the
roof.
So
the
probably
the
what
it's
gonna
be.
If
it's,
if
it's
some
kind
of
channels
in
hydroponics
aquaponics,
if
it's
a
flow
system,
ebb
and
flow
system,
we
would
perhaps
do
like
one,
don't
load
it
down
all
at
one
by
the
control
system
of
the
hydraulic
hi,
the
hydroponics.
A
So
if
you
have
many
channels
of
growing
media
up
on
the
hanging
from
the
roof,
make
sure
that
you
load
down
only
like
one
at
a
time
with
water,
because
otherwise
it
might
get
super
heavy
or
just
basically
design
it
so
that
yeah,
you
can
hang
things
off
the
top
to
get
that
third
layer,
basically
doing
three
dimensional
growing,
so
you've
got
the
roof
layer.
You
can
have
a
bottom
layer
and
you
can
have
an
intermediate
layer
so
you're,
using
the
full
three-dimensional
shape
of
the
greenhouse
instead
of
just
one
layer.
C
C
A
A
B
C
C
B
A
B
A
No,
that's
that's
correct
that
looked
when
you
do
it
and
the
low
angle
looks
like
they're
really
close,
but
no
it's
just
a
long
panel.
Yeah
hey
is
that
three
feet:
cuz.
Actually,
okay,
oh
one
consideration,
I,
think
that
these
elements
are
actually
gonna
have
to
be
four
feet:
I
Oh.
What
do
you
have
three
feet?
Because
if
you
talk
about
poly
carbonate,
I'm,
not
sure
we
can
get
three
three
foot
wide
materials,
I
think
we
yes.
A
The
standard
pieces
come
in
four
foot
with
they
don't
make
them
in
three
feet
widths.
Actually,
so
that's
actually
different,
because
if
you
do
the
roofing
material
that
comes
in
3
foot
widths
for
the
standard,
corrugated
roofing,
they
don't
make
that
in
four
foot,
but
for
the
glazing
panel.
They
make
it
in
four
feet:
yeah,
which
means
that
for
the
the
metal
panels,
I
think
you
can
get
the
raw
steel,
the
role
the
roles
of
sheet
steel,
I,
think
you
can
get
that
at
four
feet
as
well,
though,
that
shouldn't
be
a
problem
but
yeah.
A
B
C
D
A
B
C
A
So,
let's
see
if
we
can
come
up
with,
if
you
take
a
look
at
it,
click
on
the
document
that
I
shared
with
you
there
now,
let's
take
a
look
at
what
kind
of
what's
a
realistic
plan
for
for
the
timing,
because
if
so
I
mean
I
feel
pretty
pretty
confident
and
we
can
pull
some
pool
and
decent
workshop
off
I
mean.
Maybe
that's
wait
till
we
talk
next
week,
but
I
think
we
should
really
be
considering
putting
on
the
workshop.
So,
let's
see,
let's
look
at
the
timing.
What
are
we
okay?
A
B
A
C
B
A
So
until
then,
we
have
exactly
two
months:
yeah,
so
yeah,
okay,
that
sounds
good,
so
it's
quite
doable
if
yeah,
because
the
critical
path
for
that
would
mean
I
mean
if
we
look
at
the
timeline
for
preparing
everything.
That
means.
Let's
see,
I
mean
look
at
if
we're
going
to
have
the
actual
build.
That's.
A
A
A
A
A
No,
no,
what
am
I
saying
July
August
yeah,
maybe
even
more
than
that
july,
if
it's
junaid
now
you
think
we
can
get
a
workshop
announced
mommy
I
think
this
week
and
next
week
continue
on
a
design,
see
where
we
are
and
see
how
its
evolving,
but
probably
like
the
third
week,
one
more
like
the
fourth
week,
like
the
22nd,
so
about
two
weeks
from
now
shoot
for
the
announcement,
probably
like
June.
Twenty
second.
B
My
keys
might
certainly
be
cool,
maybe
something
unseen
before,
but
you
might
might
be.
I
don't
know,
gets
pretty
much
out
of
the
scope
because
at
the
moments
yeah
it
will
be
hard
to
make
something.
Out
of
this
I
mean
you
can
now
you
can
work
stuff,
some
stuff
in
sweet
home
sweetie.
You
can
work
all
the
stuff
in
cricket,
but
at
the
moment
we
will
be
pretty
hard
to
make
both
communicate
so
yeah.
This
would
be
like
I
believe
everybody.
We
talked
about
that
meeting
because
there
are
not
many.
There
is
nothing.
A
Yeah
I
mean
it's
not
like
well,
the
way
I
look
at
it
is
that
it
doesn't
hurt
to
put
those
people
together.
It's
definitely
worthwhile
and
we're
not
saying
that
we're
going
to
have
all
the
answers.
It's
basically
that
we're
starting
the
process
right.
So
we
get
we
get
progress
on
OSC
using
freecad
blender,
which
actually
we're
working
the
gasifier
right
now
in
blender,
then
Ben
Hartman
is
doing
that.
So
that's
good
and
just
you
know
just
keep
giving
energy
to
those
projects
that
are
open
source
and
continue
building
that
energy
yeah.
A
B
A
There's
there's
something:
there's
something
some
of
that
going
on
so
yeah
I
mean
I,
found
it
actually
quite
interesting
and
that's
exactly
what
the
kind
of
thing
to
be
doing
is
to
mash
up
these
software's
because
they're
so
open
to
mashing
up
right.
So
yes,
that's
a
good
thing.
I
mean
my
vision
would
be
that
we
can
generate
all
the
modules
now
so,
for
example,
we're
working
in
in
in
freecad
or
blender
between
blender
and
freak
out.
We
can
pretty
much
go
back
and
forth
right,
yes
to.
B
B
A
D
D
C
D
B
C
A
B
A
Because
the
you
know,
the
the
thing
that
I
would
like
to
see
is
so
blender
and
freak
out
our
high
power,
complex
tools,
sweet
home
is
actually
a
popular
platform.
So
what
if
we
could
design
all
the
parts
in
freecad
blender
and
then
we
have
the
readily
exportable
modules
that
you
can
use
in
sweet
home
to
design
your
house
is
very
readily.
B
C
C
C
A
So
how
does
that?
What
are
the
opportunities
and
limitations
there?
So
so
the
opportunity
is
that
that
that
individuals
have
known
no
skill
and
or
no
architecture
skill,
they
can
take
already
prepared
architectural
modules
and
make
a
meaningful
house
something
that
can
actually
be
built
all
right.
That's.
A
Powerful
now,
if
we
can't
go
back
into
blood
into
freecad,
that's
you
know,
that's
that's!
Okay.
We
can
take
floor
plans
out
of
out
of
sweet
home
right.
Just
basically
conceptual
I
mean
pretty
much.
You
have
to
go
from
the
the
sweet
home
to
a
someone
who
understands
the
modules
will
have
to
take
them
and
say:
okay.
This
is
the
build
procedure
now
right,
yeah.
C
D
B
B
A
A
A
C
B
Lily
must
place
in
my
my
sitting
room
and
then
this
kind
of
stuff
and
wait
yourself,
because
it's
little
it's
a
play
like
mush
that
were
that
that
war
will
get
there
and
didn't
add.
This
doesn't
work
in
this
whole
kind
of
adjustment
is
something
yourself
should
do
and
not
give
that
to
North
extracting
should
make
something
upper-level
out
of
that,
but
that
kind
of
you
know
fine-tuning
exactly
how
much
space
you
want
for
each
space.
A
B
A
Should
be-
and
it
can
be,
no
question
about
that-
yeah
I
mean
I.
Think
I
mean
I
personally
think
that
the
home
applications,
the
software
around
it,
the
modular
building
techniques
that
we're
doing
I
think
that's
those
are
all
killer.
Apps
I
mean
everyone
needs
a
home,
so
yeah
no
question
about
it,
yeah,
so,
let's,
let's
do
it.
So,
let's
see
so.
If
we
talk
about
this
little
potential
schedule.
A
Yeah
I
mean
jun
16,
so
that's
next
week
we
talk
next,
depending
on
how
things
go
by
next
week
we
talked
about
putting
out
an
announcement
and-
and
if
things
are
unplanned
next
week,
that
we
think
we
can
do
it,
the
the
absolute
cutoff
for
for
doing
it
like
we
can
potentially
pull
up.
You
know
go
with
announcement
more
like
July,
first
or
even
july.
Seven
I
mean
that
would
be
absolute
latest
because
you
need.
You
definitely
need
a
month
of
lead
time
for
that.
A
But
if
we
got
it
out
on
the
announcement
got
out
on
jun,
27
22nd.
That
would
give
us
plenty
of
time
about
six
weeks
to
advertise.
We
could
fill
that
workshop
and
have
a
great
time
so
I
think
yeah,
yeah
and
definitely
you
know,
let's
start
with
the
assumption
that
we're
going
to
invite
the
free,
the
sweet
home,
3d
people
I,
think
they're
in
Germany
right
those
the
developers
are
German
or
no.
A
B
A
C
C
B
B
C
B
A
C
D
A
A
D
A
A
So
if
you
wouldn't
mind
posted
on
your
social
media,
ok,
ok
that
Sam
yeah
I
mean
some
nice
stuff.
Yeah
I
mean
basically
running
the
chart,
the
micro
tractor
and
a
gasifier
that's
going
to
be
the
first
time.
We
do
that
and
that's
that's
excellent
and
we're
working
with
another
Ted
fellow
Shubin
do
on
the
open
source,
a
forest
workshop.
Basically
we're
interested
in
spawning
open
source
afforestation
enterprises
and
also
hire
cowork
orchard.
A
That's
about
open
source
orchards
are
poly
cultural,
open
source
nursery
kind
of
topic,
so
you
are
really
pushing
the
open-source
economics,
the
