A

All right march.

B

A

B

Like this, this is this is me, this is one feed. Let's see, let's get some other feeds in here.

A

March in here from the open source, panopticon.

B

Let's see if I can oh whoops, let me.

A

Try that again.

B

A

This beauty so there's a couple: let's see, there's an extra window.

B

B

A

Is my extra window, I can't find this extra window of jitsi.

B

This might be an artifact.

A

Okay, people: let's take a look at.

B

What we have for the wall.

A

B

A

The cdca home all right.

B

A

Here, all right here we go here. We go oh bonuses of the seat home, so so.

B

Right now we're doing the unthinkable, which is a full digital model. That's me uh full.

A

Digital model.

B

A

The cd cajon, so this each home looks like this here, something.

B

Let me, let me show you another page, uh cdca home 2., this.

A

Is our open source product.

B

uh Nice renderings.

A

Straight from brazil, okay.

B

The current problem statement is to, on the whole part library of the cdca home and I'll, send the link and.

A

Here you see the.

B

The the part library there's actually about 70 wall modules, all together that can comprise.

A

The entire house from the outside.

B

Walls which is 48 panels modules and then about 30 or so 20.

A

More like 20.

B

A

If I go to my log here, this is.

B

B

What what are the modules we're actually allocating the different roles in this design guide document.

A

And this is a breakup, so this is.

B

The house basically.

A

B

Floor, one through 23 23, because the double door second.

A

B

Is 24 through 47, and this is the interior walls 48 through 59, and this.

A

Is second floor.

B

Interior walls 60 through 69, so actually 69 total so.

A

The actual files are here so so this is a part library. It's a little thumbnail.

B

Of what the thing is uh we insert that into the the document now.

A

You'll see two kinds of files so say: take wall module one.

B

File, sch2 cd home 2 wall, 1, sh 3d, so that's the sweet home 3d file. If you click on that takes you to the download of that. It's.

A

Zipped now the second one is the fcstd, the freecad file right after that.

B

A

That's the thing: wherever we have a red, that means that precan file has not been generated.

B

A

The task right now is the number one.

B

A

Important because the the sweet home.

B

3D is largely for conceptual.

A

And some cab, but basically freecad, is much more powerful, so we're taking everything.

B

From katarina's sweet.

A

Home 3d into.

B

A

For advanced analysis.

B

Including structural thermal.

A

Bills of materials generation.

B

Everything else: okay,.

A

So wherever you see a red, that means it doesn't exist.

B

um So there's a bunch in red like that: fcstd 10, 11, 12 14.. You.

A

Just go through the list: whatever is in red.

B

For the freak and file we need to generate.

A

Now you might be.

B

Questioning what about.

A

Some modules that are.

B

Actually identical because there.

A

Are all the modules are pretty much similar they're, basically the same except for detail, uh there's corner modules, there's a there's window modules, door modules. So, at the end of the day, it turns out that every.

B

Single module, just about will be slightly.

A

Different because what if you have electrical and plumbing inside those which will be going into the full digital model? So so, if you think that you're doing redundant.

B

Work because the file already exists. Well, just put it over into the the red.

A

Placeholder that says it doesn't exist yet because we'll continue adding detail until those are um maybe slightly different in various ways, because.

B

Wall outlets, you know, say, there's a heat pump unit attached to.

A

One thing or say an electrical panel attached somewhere. That would mean different holes. We're talking about absolutely.

B

A

Are actually talking.

B

A

Are talking about the complete exhaustive detail for the digital model in order to enable all kinds of assets from.

B

Analysis to even multiplayer.

A

Online games everything else.

B

A

Digital model is required to take housing from inefficient to digital housing 2.0, but that's the idea. So if you don't see the.

B

A

B

Being there yet generated, how do you know how to generate it? Well, you can look at the this sweet home 3d file and that might get you.

A

B

And of the updated files you.

A

Have to go to katarina's source google drive.

B

Here so uh working there are working models, but now, since we got into the free cat, there might have been minor adjustments and changes.

A

Like, for example, as we go, every.

B

Time we hit the cad, we end up making some.

A

Improvements like, for example,.

B

A

Is a stairway great.

B

A

About we simplify that.

B

And this is the next iteration of the stairway down here, uh where.

B

Special modules.

B

A

B

A

Like select details.

B

A

This out, that's what the stairway evolved to.

B

None of the long, complex strangers but simplified design with four by.

A

Twelve, these will be actually four by twelve two by twelves are selected here.

B

A

Much simpler design right, so this is talking all about simplification at every step of the way, because.

B

Now the whole complicated stair is modularized.

A

Into these simple units that can then.

B

Be prepared, like.

A

For example, the wall.

B

Panel wall module- that's right there talking about.

A

The differences between the various panels- now you might have these uh supports pre-attached to that, and that makes the difference in that module. So that's why we're basically repeating each module.

B

And taking it to break the entire house model into discrete.

A

Parts and that is the 69 modulus, so that's the last module 69.

B

A

Some select details- all of these are downloadable.

B

A

B

You see all this red all either again, though we got to generate them. um The.

A

Idea here is also it's actually quite inspiring, because once we generate them.

B

And we actually 3d print various jigs or templates for building these modules. We.

A

Are going to set a record of how quickly it can take? We were looking at 50 hours to do these um one to two hours per module like with a skilled person, a person who's built. One of these.

B

So each one of these modules takes like an hour or two.

A

Two, for if it's a window.

B

A

But now we're getting more ambitious after thinking about the templates.

B

And workflow or simple details like how do you effectively screw things together.

A

In the most optimized way,.

B

A

On the details.

B

But now we're getting ambitious to say like okay, what if we can get our people here to do all these 68 modules in say, 10 people, one or two days or much.

A

Less than 50 hours anyway,.

B

Getting to radical efficiencies that really determine whether it takes you forever.

A

To build a house or you can build it.

B

Efficiently, so you can actually solve real problems of housing. So that's a short.

A

Intro here I'll stop here.
