Bonsai new release!

  1. M by Moult on 12 Aug 2021 #

    The old dumb walls were pretty dumb - they were a solidfy and screw modifier shortcut essentially, and broke a lot of rules for axis alignment which made it difficult for structural analysis, energy modeling, costing, scheduling, parametric layers or easy programmatic analysis. In other words - it might look like a wall, but not very useful otherwise.

    The new ones auto update based on parametric layer thickness, auto quantify, auto generate axis representations, and can join and split using multiple joint types. They also auto resolve voids, and can be used immediately for costing and scheduling.

    As discussed on chat, just for the record, turning lines into walls still exists, but the shortcut is now Shift-A with the BIM Tool activated (or you can manually press add type instance). Tooltips need help, but are a low priority for me personally due to other things on the todo list. Extrusion direction bug occurs when you haven't saved your wall thickness, so it doesn't know what to do. Bug is now tracked here: https://github.com/IfcOpenShell/IfcOpenShell/issues/1645

    @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

    Hello Dion, I recently use Create Drawing and error. You can see this

  4. E by erfizt on 17 Aug 2021 #

    I use blender 2.90 in Ubuntu 18.04 and Blender BIM 210817 py37 linux

    BlenderBIM Add-on v0.0.210829 has been released with 153 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/

    This is the 2nd birthday of the BlenderBIM Add-on. In many ways, it is also the first birthday, as the entire add-on was rebuilt at the beginning of this year. Despite this restart, the redesign as allowed us to exceed far past was the initial architecture allowed us to do. The work to date has built up a strong foundation for editing across all disciplines, and scale up to bigger models. All the features described below are pushing the boundaries of what is possible with OpenBIM and we are proud to be exploring this territory.

    A glimpse of the main tools of architectural native authoring

    The main building blocks and project library support are now available for basic architectural authoring. The tools which we expect to see: walls, slabs, columns, beams, doors, window, and furnitures and asset libraries are ready for iterative testing and improvement. Best of all, you can now insert the BlenderBIM Bunny in your projects!

    You can download the libraries from here: https://github.com/IfcOpenShell/IfcOpenShell/tree/v0.6.0/src/blenderbim/libraries

    IfcClash is back for free clash detection

    Clash detection is a vital tool in the BIM ecosystem and unfortunately the IfcClash tool was out of action for quite a few months due to technical distribution problems. These have now been resolved and we're happy to announce that we now once again have a free and open source clash detection tool. The accuracy of clashes have improved significantly, and IfcClash now works on MacOS, as well as as a standlone app, a library for your own tool, and of course, within the BlenderBIM Add-on itself.

    Drastically improved parametric costing and resource management

    The interfaces for costing, scheduling, and resource management were reworked, and now more start to integrate with one another. For example, tasks now follow the ICOM model, allowing construction processes to have inputs (e.g. formwork), outputs (e.g. walls and slabs), mechanisms / resources (equipment, labour, materials), and controls (overarching constraints). Costs can now parametrically connect not just to geometric model quantities but to task durations and resource usages as well. Cost rates and schedule of rates are now supported with import and export support, task durations may now be calculated from resource utilisation, productivity rates may auto calculate resource hours, and costs may derive from resource rates. A new formula based UI is also released, to make it easier to type in cost breakdowns and equations.

    Free model checking using the new IDS (Information Delivery Specification) standard

    Sponsored by the Google Summer of Code programme, one of our two students: Artur Tomczak finalised his work on the upcoming IDS standard. IDS is a free, XML-based industry standard way to do model checking. Model checking is a standard process of large-scale BIM projects, and existing tools are black boxes and are highly reliant on proprietary tools, or non-OpenBIM based processes. The IDS standard by buildingSMART will resolve this, and everybody will have access to free model checkers with fully replicated results. A huge kudos to Thomas Krijnen who helped mentor the project.

    IfcOpenShell users now have access to a new IDS library, and anybody can create their own specification using the new IDS webpage. Read more details about the project by Artur here: http://blog.ifcopenshell.org/2021/08/idspy-toolkit-as-result-of-google.html

    BCF API v3 support and new test OpenCDE server

    Sponsored by the Google Summer of Code programme, another one of our two students: Prabhat Singh finalised his work on the upcoming BCF v3 API and OpenCDE server. BCF is a well established system for exchanging model issues, and is a common offering by web-based CDEs. Most BCFs are currently exchanged using BCF files, but a new OpenCDE specification allows CDE providers to provide a BCF API so that anybody can manage model issues from any CDE provider from their own client.

    His API code is now shipped with the BlenderBIM Add-on. In addition, various fixes were made to the existing BCF functionality, and a new OpenCDE test server is now available for anybody wanting to develop OpenCDE apps without the cost of proprietary CDE accounts. Read more details about the project by Prabhat here: https://github.com/TestPrab/GSOC_2021

    Initial sustainability integration with OpenLCA

    OpenLCA is a well established open source LCA analysis system. We're excited to announce that we now have preliminary integration with OpenLCA. You can connect to an existing OpenLCA IPC server from the BlenderBIM Add-on and run calculations. Although the feature is still incredibly basic, it opens up exciting possibilities in more sustainable design.

    So much more

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

    Has BlenderBIM Bunny some name? Is it Male o Female?

  11. N by Nigel on 30 Aug 2021 # +4 votes

    maybe it's a gender blender

  12. M by Moult on 31 Aug 2021, edited 31 Aug 2021 # +1 votes

    Well in theory the 3D model is simply a low resolution Poisson mesh reconstruction of the Stanford Bunny which I cleaned up a bit. Also if anybody is interested in my little foray into Poisson vs my homebrew metaball based mesh reconstruction here's an article on it.

    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.

    So I guess her name is Cinnamon :D

    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

  14. M by Moult on 31 Aug 2021 # +1 votes

    @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?

  15. B by bernd on 31 Aug 2021, edited 31 Aug 2021 #

    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.

  16. G by geometrygym on 31 Aug 2021 #

    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.

    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!
