I should add that this kind of assessment of building designs is becoming a legal requirement in more and more places - the clearest example is probably Denmark where you have to do this to get a building permit, and they impose a limit of 12kgCO2e/m2/year for building design based on an assumed 50 year useful lifetime.... https://nordicsustainableconstruction.com/news/2023/january/denmark-introduces-co2-limit-for-new-constructions
I am a high school teacher. I teach Architectural Drafting. My students are between the ages of 15 and 18. I instruct my students in the use of LibreCad, FreeCad, Autocad, and sometimes Autodesk Inventor and SweetHome3D (but not very much).
I am not a very sophisticated user of CAD programs, and I would like to become so. I would like to learn Blender and FreeCad Arch. I have only really used FreeCad for mechanical types of things, using the Part Design workbench. I'm looking for resources for quickly learning FreeCad Arch and Blender. Thank you!
Hello everyone, I am Pavlos Demetriades and I am Surveying and Geoinformatics engineer and I am working on my diploma thesis with the subject "Investigating the utilization of BIM data for reuse in land management applications". I generated a BIM model using 2d drawing in Revit but lately I discovered BlenderBIM add-on and it gained my curiosity. So, i want to proceed with my BIM modeling, using BlenderBIM add-on. It is a huge chance due to I must learn the fundamentals of IFC and BlenderBIM add-on is modeling native to IFC. A thing that I want to do and I am not sure if it is possible with BlenderBIM add-on is:
Generate IfcSpaces and populated them with Cadastral Informations.
So can someone please tell me if it is possible?
Another thing I want to ask is, I am going to work on a SCAN to BIM project (Academic Project with University). The object which we are going to Scan is a Chappel. So, I was wondering if we could do the BIM modeling process using BlenderBIM add-on and Point Cloud visualizer.
Thank you
Hello everyone,
I'm Sven, I'm a former civil drafter and I mostly do BIM coordination, data validation, change management and a bit of teaching now.
Otherwise, I'm interested in computer stuff, trying to learn how to code and try to spread new innovative stuff that happen in the AEC world through a videopodcast for a few months, also.
Also, I like to cook, happen to drink rum sometimes and I live in Switzerland.
Cheers,
Sven
@PavlosDem9 it is technically possible, but not very stable, mature, or user-friendly enough for me to recommend without hesitating :)
Hi All, I'm a Developer / Sysadmin from Australia working with Linux and Open source for 15+ years and also a FreeCAD user for both work and hobby. Girlfriend is an Architect and I was looking at getting some of my own experience with BlenderBim (and BlenderCAD) and hopefully Tissue and Radiance so I can show her a possible alternative to Grasshopper & Rhino.
Hi, Im a kiwi developer, down-under in Melbourne..
Ive been working on software that takes point clouds and auto-generates a planar mesh .obj 3D model.
You can view a couple of these blender meshes, in browser : https://sketchfab.com/justgord
I'm not a Blender power user, so have a question :
Whats the best way to take a mesh such as these, and make a nice ifc/bim model in Blender ?
gord.
@justgord https://blenderbim.org/docs/users/creating_an_ifc_model.html might help :) Welcome to OSArch!

These are pretty damn good! I've used meshroom, meshlab, zephr, Recap and colmap but none have been this good with blank planar geometry as this!

My personal process at the moment is to bring the whole mesh into blender and then classify it as an IfcProxyElement, unfortunately I would not recommend as this doesn't preserve the textures just yet,
There was someone a few months ago looking at historical documentation and preserving point clouds in IFC that might be helpful for what you are trying to do, this conversation I think:

Thanks @Ace .. yeah it goes hunting for planes, lol .. its been an unreal amount of work, so really appreciate your comment!

ooh.. thats one interesting thread ... thx - I gotta learn a whole bunch about ifc :]
I’m Emma and officially enrolled in this awesome community!
Blender and ifcOpenShell offers a freedom highway for migration for today’s Architects into becoming the Architechs of tomorrow. Interesting times ahead of the AECO industry and I cannot be a spectator!
Hello everyone,
I'm Eric, a civil engineering student doing an internship at the Swiss Federal Railways “SBB”. I'm in a development department here and focus on BIM in infrastructure construction. Since the “SBB” is a state-supported company, we are very open to open source solutions in order to ensure that possible working partners have an easy start when working with us. That's how I came across the offers that ifcopenshell and Blender BIM provide and I've already carried out the first tests with ifcopenshell.

Hi @trabulium ,
I am from Adelaide :). If you have time, also have a look at Sverchok too, since it is the closest you can get from a Rhino-Grasshopper experience. I have made some Sverchok tutorials some years ago for Grasshopper users, you can check it here:

Hey @Moult
I haven't been to work for a while as I had to do my military service for the year.
Thanks for your offer. At the moment I'm still busy with simple scripts that extract attribute information from the ifc files. I have already found some examples here in the forum. But if I really get stuck I'll let you know.
Hi! My name is Sahil. I am a software engineer turned CEO (of Gumroad.com). I'm a hobbyist architect.
Hello everyone, my name is Ohm. Big hello from Thailand! I'm working towards a career in Architecture and Engineering. I hope I can be a part of this community.
Hello - nice to meet everyone. I am currently working on my Masters of Information and Data Science from UC-Berekely. I am in my final semester and have been lurking around the community for the past two months. Looking to connect with members to help us in building an ifc data set in the hopes of automating plan checking in California. No architecture experience, but looking for ways to use data science to improve the industry.
Welcome @slavingia ! A lot of Blender developers make their income through Gumroad!
Welcome @memoryofaboy ! It would be great to bring in some local knowledge about building standards and conventions in Thailand.
Welcome @rjwdata ! Sounds like you're in for a ride! The industry is generally pretty behind when it comes to clean datasets, but hopefully you'll find the cutting edge developments here in OSArch.
Hello All!!
I'm exited to be here. I'm an architect from Mexico, trying to move my BIM workflows outside propietary-software and explore other ways of working with IFC.
Having been tracking the community for a while now. And think better to join to learn more from everyone.
I am from a different industry - Wireless Network Design and Optimisation (e.g. 5G, 4G mobile networks and WiFi, including base stations, APs, antennas etc.). As you can imagine, the network design will happen in indoor as well as outdoor environments. For the moment, all of the design file formats are either proprietary or non-industry standard (same for my company).
It is good to see if we can move/migrate the format to IFC and alike formats so that wireless network designs can be also freely opened and assessed by Open source software.
In addition, I am also interested to see how we can contribute to the IFC standard to define wireless network components in a professional way (e.g. antenna radiating patterns, material RF losses e.g. permittivity, conductivity etc.).
The last part is database model in the cloud, as Moult (i have learnt a lot from you, thanks) mentioned, IFC may not be the best format to support cloud-native application developments. To find an efficient data model that can be efficiently queried and freely exchanged between IFC format will be excellent.
@Tobal welcome! As always, feel free to ask for help and we'll all learn together!
@hsong welcome! I actually did quite a body of work with utility poles and 5G antenna, and that work actually helped build a lot of the original drawing generation features in the BlenderBIM Add-on. We used IFC classes for the poles and had a library of 3D plumes as IfcBuildingElementProxy (though we should've probably used IfcAnnotation).
I think this is a perfect usecase for IFC stored in some form of database (have you seen the thread about using IFC with SQL?) as it has lots of small objects spread around geographically and often you want to just query one or two zones, or bulk process.

Thanks @Moult , it is good to hear you touch the wireless as well :). I am aware of some specific IFC classes to handle the communication network (e.g. IfcCommunicationsAppliance and IfcCommunicationsAppliance /ANTENNA), but currently are far from describe the network comprehensively. Will see how we can combine the IFC and possibly link with some external data sets.

Exactly. I have read through your thread, and some other early works for others (but no hands on the code yet). In our case, often there are more than one building evolved (e.g. campus, CBD etc.). Also currently the tricky part is to handle both indoor and outdoor in the same project. For outdoor, besides traditional 2D/2.5D GIS format (e.g. shp, tiff etc.), we also have CityGML/CityJSON for 3D modelling, I see there is possibility to extend IFC to cover both indoor and outdoor modelling (which can ease the work on both sides). Some interesting work to convert citygml/cityjson to IFC are quite promising though in a very early stage.
Sorry to talk too much in an introductory thread. Will open dedicated thread topics in case I have anything to share or ask.

Welcome!
Could you give some pointers about this quote above (papers or just write a bit about it). Could be interesting for me to have a look for academic research.
