From YouTube: FreeCAD + Blender Toolchains for Aquaponic Greenhouse
Description
With Yorik van Havre, FreeCAD core developer. We are currently planning on complete design in Blender and FreeCAD, building on MicroHouse work from http://opensourceecology.org/wiki/Chris_Reinhart_Log#Mon.2C_Mar_24.2C_2014
A
Okay,
talking
about
freecad
architecture,
aquaponics
greenhouse,
so
York
I
wanted
to
ask
you.
This
I
looked
at
the
the
guide
and
for
a
noob
on
on
freecad,
which
I
represent
gladly
I
can't
get
it
there's
a
lot
of
questions.
I
have
like
what
we
probably
want
to
do
eventually
is
I.
Think
the
quality
is
really
nice.
You
go
through
a
lot
of
stuff
and
I'm
sure
with
every
you
know,
it's
great
work.
It's
it's
I!
Think
it's
the
my
summary
of
it
is
that
all
the
capacity
exists.
It's
can.
A
The
how-to
is
like,
for
example,
like
you
tell
me,
the
IFC
workbench
or
whatever
the
IFC
capacity
I,
don't
know
how
what
to
do
with
it
or
just
like
setting
up
the
I
can't
even
open
up.
You
know
like
without
clear
just
instructions
on
freaking
I
can't
even
open
up
the
free.
The
first
screen,
because
when
I
open
up
freecad,
I
can't
eat
when
I
don't
open
from
a
file.
It
doesn't
I.
A
A
So
that
you
know
it's
going
to
be
a
little
harder
right
now.
It
might
take
us
a
bit
more
time
to
get
there,
but
I
think
we
should
do
that
because
otherwise
you
know
well,
you
know
we'll
do
the
the
greenhouse
won't
be
documented.
Well,
you
know
we
won't
have
the
proper
support,
but
you
know
can't
really
build
from
it
too
too
much
right.
So
so
I'd
like
to
invest
the
time
it
takes
to
do
it.
What's
your
availability
like
after,
like
these
couple
of
weeks,
as
you
said,
you
pretty
much
got
projects
going
on.
C
D
B
A
Or
using
well,
but
that
but
ok,
so,
let's
back
up
to
that
statement
and
the
question
is
who's
using
it
right.
If
you
want,
you
know
ourselves
to
use
it
yeah
we
can
do
that,
but
but
the
way
we
roll
at
osc
is
trying
to
get
the
lower
the
barriers
so
that
actually
everybody
can
use
it
so
that
when
we
have
something
that
we
can
work
on,
we
can
honestly
invite
everybody
to
join
that
process.
So
that's
why
I
would
say
that
yeah
from
the
Aussie
perspective,
you
really
have
to
do
both.
A
B
A
So
I
would
suggest
that
to
to
pursue
the
greater
participation
you
know
say
we
you
know,
so
he
finally
got
the
nice
blueprints
of
the
greenhouse.
We
actually
built
it
in
order
to
foster
penis.
Oh,
yes,
some
a
lot
of
people
are
going
to
replicate
I
think
there's
going
to
be
a
lot
of
interest
in
it,
but
we
can
extend
the
amount
of
hack
ability
when
we
have
the
full
documentation
in
place.
So
for
which
reason?
If
we
talk
about
exact
thing
here,
the
potential
is
huge.
A
The
potential
is
actually
I
looked
at
some
basic
numbers.
It
takes
225
square
feet
from
first
principles
using
documented
techniques
to
to
feed
one
person
like
a
full
diet,
and
that's
you
know,
I
think
the
potential
of
this
greenhouse
is
huge.
I
think
if
we
can
really
shake
the
world
with
it.
I
think
that
the
potential
is
really
high
to
do
some
breakthrough,
work
for
food
security
and
open
source
and
all
that
so
yeah,
but
that's
that's
kind
of
the
philosophy
behind
it.
C
B
B
D
B
C
B
C
A
B
A
B
And
that
is
pretty
much
faster
than
don't
freak
out,
and
so
I
often
do
that,
because,
when
your
design,
when
you're
like
designing
architecture
from
scratch,
you
often
especially
if
you
play
with
shapes,
then
if
you
already
put
the
words
at
the
right
position.
So
for
that
it's
the
same
as
when
you
sketching
we
go
with
a
pen
and
paper.
It.
B
C
A
How
many
hours
for
bass
basic
level
like
to
catch
up
to
the
freak
to
sketchup
speed?
How
many
hours
of
practice
do
you
need
extra?
I
mean
I
can
week
extra
it's
hard
to
quantify
yeah,
but
I
mean
we
can
say
that
in
the
sketchup
people
can
follow
a
simple
like
one
hour
exercise
to
get
like
basic
ability
to
do
stuff
and
blender.
Then
my
text
into
few
hours.
B
Yeah,
not
also
that,
if
you
guys
are
already
using
Sketchup,
you
can
do
the
same
with
ketchup,
so
you
can
do
something
more
like
step-by-step
conversion
between
ketchup
and
and
freaked
out
and
continued
to
model
in
Sketchup
and
import
stuff
in
free
getting
converted
it
works.
It
works
quite
well
if
you
model
correctly
in
Sketchup.
That
means,
if
you,
you
know,
if
you
do
like
clothes
objects,
well,
mottled
object
without
holes
without
foldings,
and
if
you
model
cleanly
eats
ketchup,
you
can
easily
build
architectural
pieces
or
parts
on
top
of
your
sketch
of
objects.
As.
B
C
D
C
B
A
A
Ok,
so
here's
a
here's
one
one
other
thought
thought
to
to
bring
in
it
could
perhaps
be
that
in
one
way
we
use
top
level
assistants,
like
yourself,
people
who
are
already
familiar
with
the
tools
to
generate
the
libraries
from
which
point
the
world
can
manipulate
them.
What
do
you
think
about
that
approach?.
B
A
A
And
but
the
problem
is
that
we
don't
have
a
good,
we
don't
have
a
workflow,
someone
does
something,
and-
and
it's
there
and
a
lot
of
times
we
we
we
miss
simple
steps
like
okay.
We
can
even
export
this
file
to
some
other
format.
Like
the
brick
press,
the
original
file
is
in
a
Libra
design
and
we've
got
the
misstep
files,
but
every
time
something
you
know
like
you
go
to
a
transformation
from
one
from
say
a
libre
to
to
the
step,
and
you
lose
all
the
connections
right.
A
So
you
lose
all
the
part
assemblies,
oh,
so
you
have
to
kind
of
like
start
again
and
all
that
we
don't
have
a
uniform
toolchain
defined
at
all.
So
I
think
it
would
be
good
to
the
I
think
the
strength
of
the
the
project
could
come
in
when
we
say
okay
use
this
use
this
tool
learn
it
assuming
that
we're
willing
to
teach
people
and
others
are
willing
to
learn,
and
I
think
that's
actually,
it
could
be
an
opportunity.
A
B
A
So,
in
a
deep
sense,
I
mean
I
can
just
tell
you
right
now.
Is
you
know?
Basically,
what
happens
is
when
nobody
dives
into
it,
because
they're
afraid
to
dive
into
it,
because
there's
always
a
block,
because
it's
harder
there's
that
trap
that
we
fall
into
right,
that
the
stuff
demoted
stuff
never
ends
up
getting
developed,
yeah.
C
A
Give
you
a
good
example
with
the
CNC
torch
table.
We
built
a
prototype
like
six
years
ago.
To
date,
there
is
no
open
source
tool
chain
for
the
controls
and
we're
working
with
Carosa
and
they're
going
to
go
they're
going
to
go
with
closed
source
controls
because
they
just
don't
have
the
time
right
now
to
develop
the
open
source
tool
chain
and
that
that
trap
I
see
consistently
the
open
source
community
is
falling
into,
and
we
want
to
make
a
stand
on
that.
So
I
kind
of
like
asked
affirms
that.
B
A
So
when
I
talk
about
the
tractor
I'm
talking
about
the
micro
tractor
tractor,
bulldozer,
keyline,
plow
and
backhoe,
because
they
they
are
so
similar
and
power
cube,
you
know,
because
they've
got
so
much
similar
design
in
them
that
when
you
master
one
you
can
remix.
Basically,
the
different
versions
of
the
tractor
from
micro
to
bulldozer
are
just
different
instances
of
the
same
same
modules
put
together
in
a
creative
way.
So
so
that
way
we
focus
on
creating
the
Assemblies
of
these,
and
that
becomes
the
design
challenge
it.
A
Doesn't
it's
no
longer,
do
we
have
a
power
unit?
Do
we
have
a
wheel?
Do
we
have
a
frame?
No,
those
are
there.
We
already
know
those
now
it's
about
okay.
How
do
we
actually
make
them
work
when
you
put
these
together
so
that
you
can
go
from
a
2,000
pound
micro
tractor,
like
the
the
one
we're
working
on?
Have
you
seen
the
the
image
of
that.
C
A
You
go
so
that
and
we're
also
looking
at
putting
up
a
gasifier,
an
eight
inch
wide
by
36
x,
36,
inch,
gasifier
and
the
back
of
that.
So
we're
running
this.
We're
currently
planning
a
workshop
on
this,
so
we're
going
to
run
this
on
gasified
would
actually
charcoal
to
be
specific,
so
yeah,
so
that's
coming
up,
but
basically
you
have
that
same
design.
You
put
a
bunch
of
so
that
machine
weighs
2,000
pounds
we're
also
interested
in
building
a
36
thousand
pound
bulldozer
based
on
this
module.
A
D
A
We've
got
the
other
components
like
loaders
and
buckets
and
wheel
drive
systems,
hydraulic
control
panels.
So
there's
it's
a
highly
modular
approach
that
once
we
get
the
modules
in
place
that
we
can
have
people
you
know
like
it
may
have
a
child
just
putting
together
these
power
cubes
and
stacking
them.
You
know
literally
stack
six
of
these
power
cubes
for
a
bulldozer
and
it's
actually
going
to
work.
That's
that's
our
current
strategy,
we're
testing
the
limits
of
modularity.
It
doesn't
make
sense
to
have
a
a
single
power
unit.
That's
that's
flexible,
like
that.
A
Can
you
actually
put
together
these
little
micro
tracks
into
a
bigger
machine,
so
we're
doing
some
testing
on
on
scalability
of
the
system
so
yeah?
But
from
that
perspective,
it's
very
useful
that
we
have
modules
that
we
play
with
that
we
develop
as
soon
as
we
can
so
so
you
don't
have
to
know
blender
or
our
free
cat
at
the
level
that
you
do,
but
but
just
manipulating
objects
like
in
Sketchup
modules
that
you
can
put
together.
A
That
would
be
very
useful,
for
you
know,
that's
something
we
can
have
anybody
just
start
playing
with
with
an
hour
lesson
you
know,
and
that
would
be
that's
what
I
believe
will
make
the
project
rise
to
something
from
the
engineering
you
know
freecad
geeks
and
all
of
that
to
absolute
popular
consumption.
You
know
yeah.
C
A
A
Same
system,
so
so
the
the
word
on
the
street
is
August
of
2016
we're
going
to
have
a
major
event
here
at
factory
farm,
where
we,
where
we
build,
that
certain
ecology
of
the
house
micro
house
with
aquaponics
and
energy
system.
So
you
show
a
food
energy
housing
production
system,
that's
100%,
open
source,
first,
half
of
the
civilization
starter
kit,
including
our
own
energy.
A
A
I
mean
potentially
melting
our
steel
and
by
that
time,
because
the
induction
furnaces
in
the
works
by
Joshua
Pierce
of
the
Michigan
open
source
tag
group,
that's
in
the
works.
We
might
be
rolling
your
own
steel
at
that
time
too,
so
well
be
pretty
crazy
from
umass
pellets
of
our
farm,
showing
a
totally
closed,
closed
loops
material
cycles
and
yeah.
C
C
A
Actually
yeah,
so
what
I?
What
I
would
like
to
ask
you
to
do
is
so
that
once
you
get
freed
up,
we
actually
spend
you
know
actually
hire
you
to
do
this
work.
Can
we
do
that
on
a
pretty
much,
so
you
commit
your
time
to
that,
for
until
we
we
solve
it,
and
the
first
exercise
would
be
a
simple
exercise
of
getting
then
the
the
modular
greenhouse
design
using
the
panels
that
you've
already
pretty
much
done.
A
We
get
the
interfaces
between
them
and
various
details,
but
the
concept
is
simple:
with
about
three,
you
know
like
three
main
panel
types
and
then
various
interconnectors.
We
can
build
greenhouse
structures
like
this
right,
so
so
we
want
to
get
the
detail
on
those
get
the
details
worked
out
and
but,
but
more
than
so
so
in
this
process,
that's
the
physical
product,
but
the
other
product
is
the
education
product.
B
A
B
A
A
Yes,
you
know,
base
super
basic
foundation,
stem
wall,
I
mean
we
can
we
can
consider
%
panel,
or
we
can
actually
consider
that
the
stem
wall
in
front
is
a
little.
Is
a
CB,
it's
brick,
so
we
actually
get
the
thermal
mass
in
there
so
I
mean
the
first
implementation
will
be
just
plain
panels.
Don't
worry
about
the
sea
beasts
and
Seabees?
Not
everyone
has,
but
these.
B
A
A
Of
a
thousand
gallon
is
this
size
what
we
need
about,
but
if
you
look
at
that's
you
know
that's
what
we've
done.
We've
got
experience
with
that
you
can
see
the
brick
walls
and
stucco
brick
wall
behind
the
control
panel
for
the
hydronics
we're
actually
going
to
use.
This
basically
run
the
hydronic
heating
from
this
stove
into
the
greenhouse.
D
A
A
C
B
B
A
We're
supposed
to
do
that,
we
never
did
that.
That's
what
we
will.
Of
course
we
want
to
get
to
make
this.
We
want
to
see
this
replicated
if
it's
a,
if
it's
good
enough,
it's
going
to
be
replicated
worldwide
right.
So
but
it's
not
getting
replicated,
because
we
don't
have
that
right
now,
right
all
right,
our
documentation
is
scattered
and
we
don't.
A
We
haven't
drawn
up
those
explicit
blueprints
because
myself,
Jonathan
and
Marshall
other
people
drew
up
the
last
micro
house
for
blueprints
and
we
kind
of
had
it
in
sat
in
our
heads,
but
there
were
certainly
issues
when
we
didn't
have
enough
plans
to
guide
the
people
properly
with
a
lot
of
it
was
you
know
we
didn't
have
we
didn't
go
to
the
level
of
finish
that
we
wanted
to,
because
we
didn't
have
time
so.
Okay,.
A
A
D
A
Yeah,
so
so
that
we
can,
we
can
now
start
talking
about
somebody
else
being
a
manager
of
this
project,
the
construction
manager.
During
this
event,
we
give
them
hey
here's
the
blueprints
yeah
you
do
that
and
then
we
can
actually
scale
the
builds,
because
right
now,
part
of
our
non
scalability
is
that
we
don't
have
people
that
we
don't
have
people
train
people
and
we
don't
have
blueprints
to
tie
suit
to
give
them.
You.
A
Pretty
much
we
look
at
the
the
three
model.
I
mean,
there's
procedural
steps
to
like.
If
you
look
at
those
all
those
things,
there's
procedural
instructions
but
they're,
just
conceptual
procedures:
they're,
not
they're,
not
technical.
What
I
mean?
What
do
you
call
it?
Do
you
I
mean
in
a
build
yeah,
but
look
at
this
I
mean
in
a
typical
build
people
produce
technical
drawings
and
a
general
contractor
says
I'm
going
to
take
it
from
there.
The
architect
never
tells
you
how
to
build
the
entire
structure
right.
B
A
So
we
do
the
same
thing.
We
provide
the
concept,
but
because-
and
we
have
the
full
detail
drawn
out
in
various
drawings,
when
pretty
decently-
full
detail
like,
for
example,
the
the
roof
panel
instructional,
and
then
we
get
out
there
and
we
do
it
now.
I
think
that
most
the
highest
efficiency
comes
when
the
the
person
who's
designing
actually
understands
the
build
to
so
that
it's
designed
for
build
right.
A
We
get
an
extra
level
of
efficiency
from
that,
because
otherwise
someone's
designing
something
that's
very
hard
to
build
like
I
would
imagine,
is
the
one
I
mean
not
imagine
I
know,
that's
the
case.
People
don't
design
things
to
be
built
as
a
general
rule.
Only
the
really
good
architects
might
yet
might
do
that.
C
A
A
B
C
C
C
A
A
D
A
Okay,
so
details
like
that,
but
the
but
the
basic
design
principle
is
we.
We
had
the
micro
house
standing
there
already,
and
then
we
put
the
panels
on
and
build
a
new
addition
to
that
and
with
a
greenhouse.
The
house
is
standing
already
there
and
we're
going
to
add
the
greenhouse.
Basically,
the
sloped
structure
to
the
front
of
the
micro
house.
C
A
If
you
want
the
micro
house
actually
I
can
give
you
the
detail
of
the
first
and
second,
because
the
our
house
is
made
of
modules
that
have
been
built
in
separate
workshops,
and
we
have
files
stand
alone
for
the
first
section,
which
was
just
144
square
feet
and
then
the
second
section
which
was
another,
and
then
we
built
this
section
in
between
the
two
sections.
So
was
like
three
sections
and
then
the
fourth.
A
B
C
C
C
A
C
C
A
A
A
A
A
C
A
C
A
We're
trying
to
clean
this
all
up
I
mean.
Actually
we
decided
that
the
zookie
is
not
a
long-term
solution,
because
it's
not
open
source.
So
we
need
to
limit
because
we
kind
of
go
into
this
dough
zookie,
like
the
instructionals
platform,
which
uses
an
open,
open
format
for
storing
data,
but
the
platform
itself
is
not
open
source.
So
it's
not
a
long-term
solution
for
ose.
B
C
C
A
Yep,
so
there
we
go
mmhmm
yeah,
so
we
should
do.
Is
continue
this
discussion
and
go
from
there
yeah,
but
the
problem
statement
is
to
define
out
basically
to
get
the
get
the
greenhouse,
as
I
could
write
down
the
specs,
but
the
specs
for
now
are
that
we
we
are
working
in
this
particular
case,
we're
working
in
a
case
where
you
can
add
the
greenhouse
to
the
front
of
an
existing
structure.
A
The
the
stove
burns
a
lot
of
heat,
a
lot
of
lot
of
wood.
We
want
to
do
better
next
year.
Probably
we'd
like
to
our
goal,
is
to
reduce
our
heating
needs
by
about
seventy
percent
by
having
this
greenhouse
in
front
so
like
really
minimal
and
then
eventually
replace
that
with
solar
thermal
complete
solar
thermal.
A
B
A
Yeah,
but
that's
basically
what
we
did
that
we
did,
that
that
was
micro
house
one
then
to
the
second
one:
yeah,
that's
pretty
much
what
we
did.
We
did
the
section
in
the
middle
after
that,
and
then
we
build
the
back
section
so
that
all
happened
at
end
of
2013
and
in
2014,
starting
with
yeah
I
mean
we
moved
in
here
just
last
March
and
we
had
that
one
little
unit,
and
now
we
have
a
much
more
livable
space,
much
very
comfortable
and
micro
house
ideas
is
very
tight.
A
A
And
you
can
see
that
the
Inklings
of
the
modularity
like
if
the
detail
is
correct,
then
filling
in
sections
is
easy.
I
mean
for
us,
I
mean
we
didn't.
Do
it
the
easy
way.
I
mean.
There's,
there's
not
enough
thought
given
to
the
interface
design
to
make
it
a
seamless
process
to
make
additions.
I
mean
you
I
mean
you
got
to
just
have
a
standard
that
is
well
documented
and
and
basically
have
to
think
think
out.
The
additions
be
food
in
the
design
of
the
first
one.
That
can
be
an
afterthought.
D
A
For
example,
right
now,
as
we
do
the
mic,
the
greenhouse,
we
need
to
think
about
okay.
Well,
what
happens
if
we
want
it
to
make
it
bigger
or
smaller?
You
know
we
should
think
about
all
those
issues
like.
How
do
you
is
this
going
to
be?
How
do
you
facilitate
if
you
wanted
to
add
on
to
it
or
whatever.
B
C
A
C
A
Okay,
so
let's
see
so
you're
you're
pretty
busy
this
this
week
and
then
you
going
on
vacations,
we
should
talk
again.
What
should
we
touch
in
next
because
I
mean
I?
I
I'd
like
if
you
have
any
time,
I
mean:
what's
the
when's
the
next
time
we
can
just
meet
to
get
keep
keep
discussing
this
one
go
forward.
What.
B
C
C
C
A
No
I
mean
I,
mean
I,
think
we
know
what
you
know.
We
gotta
get
your
time
and
get
the
pay
for
the
ability
to
to
get
us
up
to
speed,
to
get
some
basic
design
and
hopefully
through
this
process,
as
we
do,
the
greenhouse
the
end
product
will
be
one.
We've
got
a
greenhouse
design,
but
more
than
that,
we've
got
a
tool
chain
that
we
can
start
teaching
people.
So
so
we
definitely
want
to
get
your
time
in
on
that.
A
So
to
pay
you
for
that,
to
guarantee
your
time-
and
we
can
you
know-
just
keep
checking
in
on
these
meetings
like
the
next
two
weeks,
if
you're
available,
but
then
talk
about
you
know,
look
at
laying
out
the
work
plan
and
also
discussing
those
details
like
what
will
be
the
deliverables
and
expected
time.
Mmhmm
yeah.
Definitely.
B
A
Yep,
so
that's
what
we
want
to
do
and
whatever
you
do
like
da
key
of
course,
documented
and
I
think
you've
shown
that
you
can
document
well,
like
you
showed
me,
the
19
page
document,
the
intro
document,
that's
great.
We
want
to
I
want
to
just
put
that
online
and
we
can
continue
I'll
put
that
online
and
we'll
just
continue
working
on
that,
so
that
I'm,
basically
going
through
it
and
I'll
just
write
questions
and
we'll
make
it
into
our
official
training
course
for
Frederica.
I'm
hoping
that
after
this
with
the
greenhouse.
A
As
this
as
the
first
example,
we
can
build
a
curriculum
around
that.
So
we
can
offer
that
as
something
that
we
teach
in
our
skills
training
for
immunity,
yeah.
Now
here's
the
other
thing.
If
you
are
right
now,
we
have
so
just
tentatively
speaking
about
schedules
if
you're
going
to
be
deployed
on
this
in
June
I
could
see
that
by
the
end
of
june.
If
you
have,
we
actually
have
you
working
on
that.
As
a
priority
I
mean
we
can
definitely
get
the
design
going,
in
which
case
we
can
talk
about
putting
forth
the
workshop.
B
A
C
C
C
C
A
A
Right
now,
if
we
I
mean
right
now
on
a
schedule,
it
looks
like
it's
possible
for
the
end
of
july.
So
so
and
you
know,
as
we
go
into
june
and
like
you
know
first
two
weeks
of
june,
we'll
see
where
we
are,
then
we
can
discuss
that
if
you're
buying
chance
able
to
me
because
the
way
we
do
it
like,
if
you'd
be
a
an
instructor.
C
B
D
B
A
C
B
C
B
A
C
C
C
A
A
A
C
A
A
C
A
Part
and
aquaponics
design
should
be
a
having
a
very
exciting
thing:
cool
excellent.
We
shall
talk,
then,
and
if
I
have
questions,
I'm
going
to
keep
going
through
your
document
and
questions
I'll,
let
you
know
yeah
perfect
excellent,
so
I
look
forward
to
this.
So
have
a
happy,
happy,
happy,
holiday,
relax.
