Speckle is a new open-source platform for exchanging AEC data between clients (Rhino, Revit, Unity, etc.) with a bunch of other things.
We are developing a Blender add-on for it which allows BIM data to be easily consumed by Blender. It’s in early stages but has some basic download / upload functionality (video).
I’d be keen to see how we could make some links with your BlenderBIM efforts, i.e. turning incoming Speckle data into BlenderBIM objects and vice versa
I hope to have some time soon to take a closer look at your add-on!
@StompinTom I have seen Speckle and eyed it for quite some time I’d love to collaborate! There’s a little show-and-tell in the open-source architecture community this weekend, if you’d like to join:
Feel free to add yourself to the list:
Perhaps we can also organise an online call to see how we can get it to work My email is [email protected] and I’m generally available in the Sydney timezone. Just name a time and I’ll probably be available.
Sounds good! I can try to be available on Saturday to give a little overview of it It will be interesting also to hear others in the open-source architecture community!
Hello, I’m trying to figure out how to export the model. I get this error:

I’m on windows and tried already to uninstall and install everything again (with the remove button; actually having version 0.0.200.328). I’m doing a really simple project using the archipack add-on and the button to set everything in ifc format for the blenderbim add-on provided in archipack.
I’ve followed the tutorial on blenderbim website and even with those simple steps it seems the exporter doesn’t work since the ifc file can not be read from other Softwares of ifc viewers.
Feeling a little dumb not being able to figure out what’s wrong. I really appreciate all the work but encountering some miss-steps in my workflow right now; ifc-blender-freecad combination is really powerful, hoping to get it right.
That error looks as though it may come from Archipack. There have recently been a few modifications to have Archipack and the BlenderBIM Add-on work together, but I think our release schedules are a bit out of sync.
I’m surprised the tutorial on the BlenderBIM Add-on website does not work. Does it produce an IFC file? If it does, it should be able to be read. One possibility is that it exports an IFC4 file, but your software only supports IFC2X3. For example, I know older versions of FreeCAD bundled an IFC2X3-version of IfcOpenShell.
Feel free to send me a private message with your timezone and we can organise an online screenshare using Jitsi Meet and I can help debug your issue! If you like IRC, both Stephen Leger (Archipack) and I are online on the ##architect channel on the Freenode network.
Hi,
There is a known bug related to archipack Ifc collection structure, not adding Reference points into IfcBuildingStorey collection. Blenderbim is moving fast, but we are working together to adress those issues.
Until next archipack release, add Reference points in the collection, and add IfcBuildingStorey/ prefix to reference name, so it does match storey collection name.
IfcBuildingStorey/Reference.xxx -> Reference.xxx
Thanks for your time! With a little more patience and cold mind I was able to export/import a basic ifc file in blender --> freecad. Still some troubles with the archipack workflow but I’ll try to apply the advice of Stephen once again and see.
2 weeks later since the last release, over 30 new OpenBIM features and fixes in a brand new BlenderBIM Add-on v0.0.200413 release! Get it today: https://blenderbim.org/
New feature to validate the syntax of IFC files, in case you receive a broken IFC file
New support for viewing and overlaying BCF snapshot images on top of the model to compare issues
More stabilisation fixes on multicore IFC import
Support added for BCF header files
IFC import now supports multiple materials for a single object
More robust material imports for BIM authoring tools that still use the deprecated IfcPresentationStyleAssignment or have missing styles (yes, Revit, that’s you!)
Experimental multicore support added to IFCClash
The IFC2CA project has joined the IfcOpenShell umbrella!
BIMTester now bundles test definitions so you get tests out of the box!
IFCDiff now checks inverse relationships for changes too
IFCDiff lets you specify filters for checking specific inverse relationships
BCF snapshots with varying aspect ratios are now supported
The IfcProject entity is now a real object in Blender, which can be queried and exported with all of its metadata
BIMTester now supports the full Project setup MicroMVD definition
New optional GUI in BIMTester for people who don’t like command line
IFCCOBie has various fixes for strange formatting on wrapped data
BlenderBIM Add-on dependencies repackaged inside add-on, to allow for native Blender install and uninstall procedures
BlenderBIM Add-on Uninstall feature removed, as it is now obsolete in favour of native Blender uninstall process
IFC spatial elements without any geometric representation are now imported
Invalid Psets without any properties (as created by Solidworks) are now imported
Diff import support has now been upgraded to the non-legacy import mechanism
Rebar is now treated specially to prevent BREP faceting, so it retains its parametric swept disk solid behaviour, and is easier to edit, imports 10 times faster and is 10 times smaller in terms of filesize
IFC import has an optimised spatial tree processing algorithm to handle files which have hundreds of sites and buildings for precinct BIM models
Psets and Qtos can be selected from a filtered list for easy user discoverability instead of having to know the IFC spec
New IfcExportSettings factory to let the BlenderBIM Add-on be integrated with other Blender add-ons like ArchiPack
Improved ArchiPack compatibility - export parametric IFC objects from Archipack!
Repository code cleanup of old experimental files
Fix for potential infinite loop during export
Fixed some invalid schema exports related to void/fill/projection relationships, and material assignment related to linked duplicate objects
New support for import and export of the IFCZIP format
New support for BCF component visibility settings, colouring options, and selection sets when viewing BCF topics
New support for BCF orthogonal camera scale factor
Also, a group of free software developers have joined to create the OSArch Community .
The Open-Source Architecture Community brings together like-minded users and developers who share a common goal: that the built environment can be designed, constructed, operated, and recycled with free software , increased transparency , and a more ethical approach.
Naturally, very closely aligned with this is to support and implement open data standards to the highest quality possible, and promote its use in the industry.
I thought I might try and record some mini demo videos on how parts of the BlenderBIM Add-on works, because it is quite feature-packed and can be quite daunting. Also, recording videos is faster than writing documentation
Feel free to check it out - here’s the first to do with section planes, which is today’s new feature.
It’s another 2 weeks, so here’s another 30 new fixes and features in the v0.0.200428 BlenderBIM Add-on release! Get it today: https://blenderbim.org/
Highlights include bundled classification system selection including Uniclass and Omniclass, create and consume property set template definitions, reload IFCs, import/export with CSV, and section planes!
first of all, the work your doing on this is astonishing.
Second of all, I just started learning Blender, because I’m looking to transfer my whole workflow to open source software and I had a lot of hope in it to replace the modeling part. I’ve been sitting on it for the past two weeks, hitting some serious obstacles, looking for workarounds, giving up and starting over. Then I finally found your plugin and it seems to be way more than I was ever hoping for.
I’m really excited and also really frustrated, because I can’t seem to find any documentation on all the amazing functions you’re adding, so I was wondering if I could help in any way. Could you perhaps give me a quick crashcourse so that I could start writing it for you?
I’m also convinced this would be a brilliant solution for all the architecture students in the world. The debate about the best software for architecture will probably never end, however providing an open source solution we could teach to all the students during their studies and let them use it for their own projects even after they are done studying would be huge.
@jan.filipec thanks for your support! You’re right, there isn’t much documentation, which is why I tried to start recording videos, since it’s faster than writing docs
There is documentation I started (but is now outdated and some parts misleading, so careful when reading it) here: https://blenderbim.org/docs/
I’d love it for you to contribute! It’s all open-source! I’m in Sydney, Australia, so perhaps the easiest way is for you to catch me online on IRC ##architect channel on freenode, or recently I’ve also been hanging out on blender.chat under the name Moult, so find me online during the Sydney timezone, we’ll organise a screenshare, and do a crash course that way.
Working with an Archipack project which has become fairly large, I am trying to export it to .ifc (after using the Archipack tool for making the object into ifc classes, which worked fine). The export fails everytime however with the attached error appearing in the console. If selecting none ifc classified objects amongst those to be exported makes the export fail, can there be a mean of selecting only objects classified as ifc classes to ensure the export works, or is there a different reason why it does not work?
In the next one,
