    @MexiKiwiMike
    There is also a little test library of elements that makes starting quicker,
    It's super quick once you know the hotkeys and the walls are loaded:
    Click -> load IFC library (below create IFC project) -> once loaded click the paper clip on the right to load each element

    how about this blenderbim-demo-library.ifc files. Lot of viewer do not display them. The one I use very often even crashes. I came around these files here ... https://community.osarch.org/discussion/comment/8524/#Comment_8524
    Are there any more information available? May be at the wiki or at buildingSMART?

    cheers bernd

  • @bernd that file is not meant to be displayed by a viewer - it is a partial file containing only library data, but no project. To be legal (and thus viewable) I guess I need to wrap it in a project, even if it seems redundant.

    Thanks for bringing this to my attention, I thought I had once seen libraries used by themselves by an official buildingSMART example but I cannot find it now, and only find evidence that libraries can only exist wrapped in a project. Perhaps @geometrygym might know?

    I relized myself the missing of the IfcProject. Since it has ifc file ending we need to do something in this regard (IMHO). If it has ifc file ending people will try to open it in a ifc viewer and will fail. The viewer could even crash. Viewer developer might say BlenderBIM does create non standard ifc. We should not let this happen.

    Neverless I like the idea to use ifc to save libray data.

  • Hi Dion, you're probably referring to a geometry gym sample that isn't compliant with the specification. At present the IfcProject is a mandatory singular concept in an IFC serialization. Perhaps this could be relaxed to be an IfcContext (supertype of IfcProject and IfcProjectLibrary) but at present the library needs to be declared by an IfcProject to be legal. It would need a schema change but also some working groups have explored ifc "snippets" which are isolated IFC data sets not necessarily in context.

  • But the real Rabbit (i.e. the one in all the photos) is my cute female pet bunny named Cinnamon. She can do tricks and her portfolio is here.

    Bet she speaks Python!

  • @bernd @geometrygym cheers, I've now fixed it. https://github.com/IfcOpenShell/IfcOpenShell/commit/a1b462a83b1b795addf77951533a54ab5140e1b2

    I still need to build a bunch of project library editing related UI - so that it shows up in the tree, and you can manage multiple library declaration (right now, only a single library declaration works). But at least it is legal now :)

  • Hi, I need help with the file “blenderbim-demo-library.ifc”. When loading in “IFC Project Library”
    I’m getting an error message: “Ifcopenshell.Error: Unable to parse IFC SPF header”
    Thanks in advance!

  • No love for M1?

  • @Carozo it sounds like you have not downloaded the library file correctly. Try file save as from this page: https://raw.githubusercontent.com/IfcOpenShell/IfcOpenShell/v0.6.0/src/blenderbim/libraries/blenderbim-demo-library.ifc

    @VDobranov not at the moment, no, we don't build for ARM. Would you mind posting at https://github.com/IfcOpenShell/IfcOpenShell/issues/1702 ? I think to solve it, we need to purchase an ARM MacOS machine. Perhaps we could fundraise for this?

    Just to try the waters: are there any means to donate on particular goal?

    BlenderBIM Add-on v0.0.211031 has been released with 187 new features and fixes. It's our built environment, help support the BlenderBIM Add-on: 100% free and open source software that lets you author and document BIM data fully to ISO standards. It's built by the AEC community, for the AEC community. Get it today: https://blenderbim.org/

    Let's get into the details.

    Upgrade to IfcOpenShell v0.7.0, for a 35% - 2,000% (yes!) speed boost and new developer toys

    The biggest aspect of this release, which is why we delayed it for a month, was an upgrade to v0.7.0 of IfcOpenShell. This represents a significant impact for developers, thanks to the tireless efforts by aothms. We will now benefit from geometry caching (in future releases), a new drawing generator (WIP), a huge speed boost ranging from 35% to 20 times faster depending on what you're doing, visualise bounding boxes and fill areas, SVG analysis, and version tags. Users can start to play with the ongoing drawing features in upcoming daily builds, and generally see things faster everywhere.

    New testable code architecture

    On the Python side, code has been rearchitected to allow for a more robust test framework and UI rendering. For developers, this represents a maturation of the codebase and developer community, including code standards for licensing, QA, style (black), linting, and TDD. Over 800 tests were written for this release with the new architecture, spanning from unit tests to full integration tests. For users, this is largely responsible for the staggering 68 bugs zapped during this release, so users will likely notice less regressions, and that the BlenderBIM Add-on will start feeling more and more like a native authoring tool.

    Partial project loading support

    You no longer need to load an entire project. By enabling advanced mode when importing, you can filter what you want to import, allowing you to load huuuge models much faster and only related to what you're planning to edit or review. Choose from filtering by location or by type, as well as new collection hierarchies.

    Parametric geometry is now default

    One of the biggest user impacts when editing is now that parametric geometry is default. You can now push and pull things as a mesh, but under the hood the parametric geometry will be preserved when possible. This leads to much more natural modeling and less paying attention to geometry modes and updating representations. This feature is also a leap of faith in standardised parametric IFC geometry, so keep an eye out for issues!

    Improved construction scheduling

    Construction scheduling continues to improve with bugs fixed around date calculations, rendering animations, real time date visualisation, Primavera P6 XER and resource import support, a new Ifc4D command line tool, improved formwork calculations, and more.

    So much more

    Other notable improvements include more point cloud support, user UI presets, real time type filter, bulk property and attribute editing, a few MEP system visualisation tools, and upgrades to the ownership and context editing modules. A huge thanks to the growing volume of new contributors who are joining the team and changing the industry. You can too!

    @Moult : Do you know if blenderbim has been tested with the real-time collaborative addons Mixer or Multi-User for blender? It would be awesome if they can be combined in order to get real-time IFC-editing and engineering capability for multiple users using blender. See this post for info on them.

    Hi, I have an issue setting up BlenderBIM. I am using Blender 3.0 so that could be causing the issue.
    I tried following Dion's quick demo but I don't have any of the circled options
    I do have BlenderBIM checked in addons and I do have the IFC Derived Placements option, so it seems that BlenderBIM is installed. Any ideas?
    EDIT: Seems I missed the create IFCProject step, it's solved now

  • @HaukMorten unfortunately those real-time collaborative add-ons work only with Blender, but there's a missing step to get it to synchronise with IFC edits. So without testing, I can tell you that out of the box it won't work (yet).

  • Thank you for your response @Moult . Well, it's a wish for later then. BlenderBIM still isn't mature enough for us to use in a production environment yet in either case, but perhaps some day in the not too distant future I can wish for some development funding internally to try to at least figure out what needs to be in place for us to begin to use in for engineering. I've already used it for geometry editing of IFC's that wouldn't open i Revit at all. Once one gets the hang the shortcuts, editing in blender is so much smoother than in Revit!

  • BlenderBIM Add-on v0.0.220130 has been released with 252 new features and fixes. It's our built environment, help support the BlenderBIM Add-on: 100% free and open source software that lets you author and document BIM data fully to ISO standards. It's built by the AEC community, for the AEC community. Get it today: https://blenderbim.org/

    It's been 3 months since the last release. Unfortunately, development had been put intermittently on hold due to various factors, including presentations being prepared for the Boao Forum for Asia ISTIF conference, FOSDEM 2022, and the 1-month online course on OpenBIM and Python programming by E-Zigurat. In addition, there was a one month break from development during the holiday period. It's a marathon, not a sprint! :) Happy 2022, and we're back!

    Let's get into the details.

    Optimisations to authoring and geometry caching

    A huge kudos to the exceptional optimisation work by Thomas Krijnen. Especially when modifying large files, expect operations to be in the scale of 100x faster, especially when dealing with proprietary BIM exports. Bulk movement checks are a minimum of 5 seconds faster. Importing files with booleans can be 2x to 3x faster. New performance logging in the core means that optimising is far from over.

    A new geometry cache is now implemented, so reopening the same project will be much faster.

    Increased stability

    Native authoring stability was a huge priority for this release. An additional 450 tests were written since the last release, and 76 bugs were fixed. This is the return on investment in the new testable code architecture which was revealed in the previous release.

    Brickschema integration

    Brickschema is a way of describing system topologies for building management systems (BMS). When we talk about digital twins and clear away the marketing buzzwords, we're really talking about things like Brickschema and live building sensor data that Brickschema can reference. The BlenderBIM Add-on is the first in the industry to start providing a graphical Brickschema authoring environment that integrates with IFC.

    It is now possible to create a 2-way link between IFC BIM models and Brickschema BMS models. This is possible due to new support for managing IFC libraries. Brickschema authoring is still very new, but it's ready for basic testing!

    New bulk property editor

    In our quest to help clean OpenBIM data in the industry, an incredibly suite of bulk property editing tools are now available by developer Vukas Pajic. Includes bulk renaming, data type changing, removal, and adding properties.

    Chipping away at drawing generation and MEP support

    Drawing generation is a huge task that still isn't ready for user testing, but all the same work has been done. Including improved section cutting booleans, geometry caching, fixing "the torus problem" for steel sections, new 2D elements in the demo library, paper scale annotations in the viewport, performance testing, native IFC roundtripping for annotations, associating objects for smart annotations, annotation variables, drawing sheets, and improved UI.

    Also ... more rabbits!

    MEP is one of the areas not really supported by the BlenderBIM Add-on but that is now changing. Support is now added for different types of building systems, selecting different types of systems, and displaying distribution ports.

    Better docs and building for developers

    A number of fixes to the build system makes life easier for developers on different environments to build IfcOpenShell thanks to Thomas Krijnen. Also really exciting is the new super secret demo module tutorial and improved developer guide for new developers who want to learn how to build your own BIM application on Blender and extend the BlenderBIM Add-on.

    So much more

    Other notable improvements include new UI grouping, IFC to P6 XML export support thanks to developer myoualid, viewing IFC metadata prior to loading with one-click IFC4 file upgrades thanks to developer Gorgious56. Blender 3.0 is now officially supported. In addition, new support for parsing EXPRESS schemas in the interface has been added, in preparation to support IFC4X3. The testing process for IFC4X3 support has begun, with the hundreds of tests in the suite being redirected to check IFC4X3 support, with very promising initial results.

    A huge thanks to the growing volume of new contributors who are joining the team and changing the industry. You can too!

  • Hello,
    I installed Blender version 3.1.0 and it doesn't work with BlenderBIM Add-on v0.0.220130. I didn't have a previous version installed.
    Is it necessary to use different versions?

  • edited March 12

    I just downloaded blenderbim-220309 developer build from:
    https://github.com/IfcOpenShell/IfcOpenShell/releases

    I tried to install the blenderbim-220309-py39-win.zip on Blender 3.0.1.
    I get the following error.

    No module named 'blenderbim.core.document'

    Thanks @theoryshaw
    I installed version 3.0.1 and it works all ok. I am not sure how to change the python versions and where for version 3.1.0. This is good for now.

  • https://github.com/IfcOpenShell/IfcOpenShell/releases

    The blenderbim-220316-py39-win.zip is not working on Windows with Blender 3.1.0

  • edited March 17

    I think you have to use the "-py310-.zip" file
