 FreeCAD is a huge project much bigger than only for the architectural field, so we are several from the FreeCAD developers here They are here raise your hand Yeah, they're there. So if you're interested in the project and seeing it Come talk with us later during the weekend and we show we show it's more in detail. We explain it's all so This is me. Yeah, I say I'm one of the main developers because there is no really real Structure in the in the FreeCAD projects like everybody can be a main developer. It's just that I'm there for more time This is how to contact me. This is my architecture office. I live in some in Sao Paulo. I'm not Brazilian I'm Belgium. I'm a fake Brazilian, but That's our office. That's what we do with it's just small two people office and We use FreeCAD more and more. It's beginning to be to become our let's say part of big part of our tools we use almost only free software at work and just a couple of things we Still use a couple of free options that are not free software, but most of it now is is open source software so for who is totally New architectural design. I'll explain quickly what we do actually This is what how Architects used to work before you had those big drawing boards and you were just drawing seriously like that and This is actually what you do when you Were draw when you draw Architecture you have a building and you make the drawings of the sides of the building and you also cut Through the buildings that are those Plans there and so you make those sections vertical sections and horizontal sections which are plants Through the building and you basically draw all these drawings so people who build the house Read those drawings and now what to build and how to how high how thick and and so When the computer came in Like 20 years ago This is AutoCAD which was the big software that architects began to use and AutoCAD Is was at that time, but it's today's bit more, but it was basically a Computerized drawing board so you would draw in AutoCAD the same way as you were drawing on the Drawing boards you were drawing lines and drawing all those those things This is a typical architectural drawing so you basically draw the Cut Building and you annotate a lot of stuff in its dimensions so people can read the dimension know what What size is each thing and a whole lot of annotation this must be concrete this must be Metal and this must be built before that and those kind of things these drawings are interesting because they are from Alejandro Ravena who is just won the Pritzker Prize, which is the Nobel Prize of Architects and This is open source now these are his famous project. It's a house for it's a popular house for poor people and they don't have a lot of money and So he built this project, which is a half half good house. That's the idea of it and This is fully open source now you can find it online So this is What This is what beam is now Basically, we don't draw anymore we model in in 3d and So you model things and then you You can cut through them the model and Extract the the drawings so you don't Model and you don't draw anymore your model in 3d and then you extract your Your drawings from it And this is the kind of drawings that you can obtain in free cat directly from your 3d model and Of course beam is much more than Just a 3d drawing inside the model you have a lot of information and So from your model, that's the whole thing of what we call now beam which is like Beam is hard to define actually it's what All architects would talk about beam. Yeah. No, we don't do cat anymore cat was the 2d drawing I showed you now we do beam, but it's actually pretty hard to know what is beam actually because there are lots of People with different interests and companies who would sell you soft beam software and each of them has a different Explanation of what beam is but let's say it's the 3d model with a lot more informations, you know all the those Notes I was showing you in the earlier slide These all notes would be like information that's contained Inside the model and then from your model All the walls have information about what material it's it's made of and such and so you can extract that information from your model and build all those kind of tables drawings Renderings because you have all the Material information and so in your model is not just the geometrical 3d. It's The wall information about the building that is stored inside the inside the model That's the interesting part of beam. That's what we call how we could define it actually So 3d model which with much more information in in it So beam is used. It's like everybody talks about beam in some countries here, especially in Europe, it's pretty much it's Used a lot and the governments are You know that when you will build a house you have to ask permission to your government to your city or something and then we they will give you an authorization to build and and You have to give your project to them to to obtain the authorization and in in most European countries and in the United States as well they begin to I think they are of all like deadlines in a couple of months or years You will have to give them a beam model to obtain the authorization But in some other countries like in Brazil People architects still work mostly in 2d like before that they won't use 3d models a lot so it's something in between that's getting used but not totally used everywhere and and The last line here is the real problem You have two firms Which are autodesk and Nemechek who's selling about 100% of the beam software used in the world and it's not something cheap I think one license of one of those things cost about about five thousand dollars something like that and for one person in the office, so you have 20 architects it's 20 times and And So they are like present as all-in-one solutions where you have your beam model and you do everything only in that software you Extract the quantities you do the calculation you do everything in it and They have that aggressive domination tactics that they Go to university they talk with Architecture teachers in the university and they make deals with universities so universities only use those software and students and teachers get it for free so that they this Maintains a state where Students and teachers only know that software and after that they won't change easily when they are being that their professional life And they have also file formats which are like every year there is a new version of the software and The old version doesn't open the files of the new version. So they like force you to to upgrades every year and This is really seeing the problem if you type Revit architecture in Google you get this and You get the you it can go along and you will see that all those buildings actually look the same So it begins to have a style That oh, I'm talking a lot too much. So you begin to have a style that is Given by the software the software end up configuring how architecture looks So there is a good side which is That there is for the first time Open formats which is IFC and this is maintained by a consortium a bit like HTML on the on the web and It's human readable So it's just lines that reference each other that's a structure a typical structure of an IFC file And so now we have an open file format to describe being building and it's a It's not perfect. It's far from good, but it's the best thing we've ever had in in the construction world So, yeah, everybody knows blender here Why blender for those 3d? Why don't we use blender for architecture and it's true. Why not? We use it a lot at office. Actually, it's fast. It's match mesh based Blender is Extremely cool to work with you have those things that come from the game engine of blender so you can work architecture in in real situation And it's thrilling you wouldn't be able to do that with those commercial software like working like if it was in a game And this is tremendously Interesting to work architecture that way and Of course it you can do the rendering directly in blender. So you have like the whole cycle of the things you must produce in the same software So why not? Actually, I think because a blender is Smash base is made for speed and you know when when you draw There is that direct connection between your your brain and your your hands like you're on the phone and you're sketching And when you look at your drawing something came out of it because there is that direct connection between your brain and your hands that you don't need to think and Blender is so fast that you can almost Have the same thing with 3d modeling like you're thinking about something else and when you see you modeled something cool And so this is tremendously interesting, but for actually we also need precision tools something slow that make things exact like it's 20 millimeters not 21 and For that there is actually free cad and and Freak at it is a Technical 3d modeler. It's not made for organic and nice thing. It's made for precise exact Geometry and it's for me. It's the other side blender is the creative side and free cat is the the Technical Sears side and you need both you cannot work only with one side and there are those advantage of Advantages of free cat that would I would explain the outside for who is interested And we have a special architecture module in free cat which mostly me and the other guys here contributes to and So it's really we made it to work with blender So it would take your blender mesh as long as they are cleanly made and turn them into architecture model So this is the look of free cat. It's very very basic interface You can do all the things we were I was talking about earlier. You can cut through your models and extract those drawings You can also there is a spreadsheets Module in free cat where you can extract all those volumes and quantities are directly read from your model So you can extract information from your model. So it's perfect to build beam model and These are a couple of projects We make made at the office or this section is Taken from this model. Of course, it's a bit reworked in the game But you can really extract most of your stuff from your 3d models Another project. This is when you heat it's exported to IFC so you can Import it in even in those commercial softwares another project. This is the plan that Comes from it's also a bit reworked afterwards. This is a model from Jonathan here Also You have those free cat gives you those interesting Ideas about how you could not any more show architecture like traditionally with drawings, but it's a bit like Ikea Manuals and you begin to have because other people use free cat that are not architects and give they give you ideas that you wouldn't have normally that's The other people would present thing Different way we also have free cat is more and more used for 3d printing and So this also gives us new openings and possibilities That that are closely related to architecture and that we don't think normally But those guys are here around us and so we communicate and we get new ideas This is the structural analysis module. This is a work of Ben here And you can also Study effort real-life efforts in your model and see what happens in your models You could do that also for Termical Simulation that's not yet there yet, but all the structure is there to be done This is another piece of software which excels to it home 3d and it's interesting because it's it's a toy You would say this is not an architecture software This is some toy to place your your Furniture inside your house, but it's tremendous interesting because it's a tool that anybody can use who has with no architects And the result of this program can be important in free cat. So you could really have people designing their own house and you be able to turn that into technical information and This is also extremely interesting and this is another project called wiki house and they build Those house out of Big plates of wood that are cut by a machine and then you assemble the piece of wood to build houses So we in free cats. We also are how to do that too and Use that it's an open-source project. You can take their files and we are like trying to Bind all those things together We still have I'm finishing we still have one small problem is that Working to be we still need a bit of drawing sometimes hand drawing and There is no real good open-source solution because architecture you saw the drawings they are gigantic and Usually all the Available applications like Libre cat and and so the Enscape would crash miserably when we have those enormous drawing But we can do as much as we can extract as much as we can from free cat and we could reduce that Needed hand work at something minimal. That's the aim. What we're that's what we're aiming at actually And That's what's coming in free cats in what we're working on now Actually battery I've seen support. I've see is vast word. We need to work with it better and have more Convenience tool to draw walls and that those things directly in free cat And direct editing which is like pushing your your walls manually on the on the screen And Well, that's it Thanks for listening and this is our forum The free cat forum. That's where everything happens where all the community where all the talk and If you're curious get involved there because there is a lot happening there These are the website
