BlenderBIM Add-on v0.0.210605 has been released with 186 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 mammoth release is the first release since we announced that the BlenderBIM Add-on has been awarded an Epic Games MegaGrant. This funding will help accelerate our roadmap in providing stable geometry processing for the entire AEC industry, vital 2D drawing support, and cross-disciplinary features. Similarly, we are proud to announce 2 sponsored Google Summer of Code students who are making outstanding contributions to the project!

Blender 2.93 support, even faster IFC4 imports, and we made the add-on 3x smaller!

With the latest release of Blender 2.93, the BlenderBIM Add-on now supports the latest version. For those still on Blender 2.92 and below, developer builds are still available on Github.

Users will now also experience a huge speed boost which may be 8 times faster when importing IFC4 files with tessellated meshes thanks to optimisation works done by aothms. The new drawing system is now in progress, which has led to a huge reduction in the BlenderBIM Add-on filesize. The add-on is now three times smaller - all the features you love (and more), shipped in only 40-60MB (depending on your platform), compared to up to 180MB previously!

New native parametric wall and slab authoring tools

The new parametric engines give us a glimpse what native IFC geometry authoring can look like, with the new wall and slab authoring tool. Creating and editing walls and slabs are now super slick with sketch-generated walls, hotkeys, auto generated axis, quantities, joining, splitting, mitred joints, and more.

The new object type insertion interface lets you insert any object from your project collection. A new project library panel lets you import types from other IFC projects, paving the way to an asset library of IFC objects.

New cost planning tools

An entirely new cost planning module is available. Did you know that if you worked with native OpenBIM IFC, your cost planning is directly integrated with your BIM model? The BlenderBIM Add-on is the first in the industry to provide native IFC authoring for cost planning. With support for model linking, automated quantities, new quantity take off tools like a formwork calculator, and arithmetic operators, subtotals, and more, imagine a future where our BIM models don't have to deal with lossy import and exports, and tedious model mapping.

New construction sequencing tools

Like cost planning, an entirely new construction sequencing module is available, with the BlenderBIM Add-on an industry first in providing native IFC authoring for construction sequencing. Tasks are created directly integrated with the OpenBIM model, with support for task trees, critical path analysis, gantt chart generation, floats, task dependencies, and more. You can also visualise and generate construction animations with speed controls. Also supported is imports from P6 XML and MS Project.

Progress in structural support

The BlenderBIM Add-on now has improved support for structural analytical models, with more nuanced controls over editing loads and coordinates and axes. Work is still in progress, but it is exciting to see where we've gotten to so far!

More support for the latest OpenBIM standards

If you are a BIM poweruser, staying up to date with OpenBIM standards is made easier with open-source, as you can really tinker and get into the details of new technology. Our GSoC students Artur and Prabhat have been working hard on the new Information Delivery Specification (IDS) validation technology support, and BCF XML v3.0 support. Similarly, Moult has released a new bSDD version 5 API library, along with new Lighting geometry support, and aothms and civilx64 has been hacking away at the new infrastructure geometry support. Other interesting things to take note in the IfcOpenShell repository include a new IfcCityJson module by LaurensJN. Check out the repository and support all of these interdependent projects!

So much more

As usual, a ton of bugfixes, minor usability improvements, and full details are elaborated in the detailed changelog below.

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

Hi Dion, congrats for your work.

I'm testing this release and get problems with user pset. I generate my own psets with "IfcProperty Set Templates" panel but when I try to assign this Psets to an object with "Ifc Object Property Set", the property set is asigned but I can't edit the properties values (are missing). I tested with "IFC2X3_Geolocation.ifc" file with the same results. Psets are added but can't edit properties.

J by Jesusbill on 17 Jun 2021 # +1 votes

Hey @avico I think this is related to the issue posted here

You can try and grab the nightly build of BlenderBim with the bug fix

E by erfizt on 17 Jun 2021 #

Hi, do you know where to find the most complete documentation/tutorial about new blender bim? I am new to IFC and only know about blender. I currently install new version of Blender BIM, try to add Dumb Wall but no dumb wall in the menu

A by Ace on 18 Jun 2021 # +2 votes

hey @erfizt, the dumb wall has been updated to a smart wall of sorts, have a look here at moults' demo of the tool:

first try and work with the latest version of blenderbim (daily releases) found here:

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

This is a great video for explaining the concept of IFC:

but I think it's easier to get started and then refer to it once you are in it,

Then for video demos (which I follow easier than text) you've probably watched this old one:

the tools have been updated but this is still useful for getting started.

Then for the wall tool, this video demo is great:

Then there have been quite a lot of additions to the costing & scheduling portions

It changes very quickly so the documentation can't really keep up, contributing to the wiki is one of the ways users can assist

A by avico on 18 Jun 2021 #

Hi Jesusbill,

thanks for the reply. I will test-it.

Another thing: I see a lot of interesting new funtionalities. There is some place with information about how-to use them?.

Last year I tested BlenderBim and FreeCad as autoring tools for BIM in Civil Engineering (roads and structures mainly) with good results ( If you adopt a convenient workflow, I think they are very useful and in many cases more flexible than commercial sofware) and new functionalities (cost schedule, construction sequencing, etc.) are more interesting in this context.

J by Jesusbill on 18 Jun 2021, edited 19 Jun 2021 # +2 votes

@avico I think @Ace with his post above aced it in summarizing the current status. The last two videos showcase some of the latest functionalities

J by Jesusbill on 19 Jun 2021, edited 19 Jun 2021 #

@avico also look at the wiki like here

C by carlopav on 1 Jul 2021 #

@Moult very interesting progress in BlenderBIM!

A question about the walls of the video above. You mentioned it's important to have the geometry aligned with the x axis of the local coordinate system of the object. I agree and that's what I was trying to do with FC also, having the LCS.XAxis of the object aligned with the wall axis (bottom center line of the wall). But does this come from some standard? Or can this be an implementation agreement between BlenderBIM and FC default wall? Is there an IFC a suggestion about the relationship between Wall LCS and its solid representation? thx :)

M by Moult on 1 Jul 2021 # +1 votes

@carlopav This comes from the IFC standard for IfcMaterialLayerSetUsage. As a rule of thumb I almost never invent anything, but instead follow the standards.

A by avico on 30 Jul 2021 #

Hi all,

maybe this is not the right place to comment this but I don't know where I could do it.

I'm testing the latest buid release (blender28-bim-210729-py39-win) with blender 2.93 in windows 10 and get some issues when assign user properties in more than one object. I select all objects I want assign a user pset and assign them (in object properties panel) but only the first object selected get the pset. In the same way, if I want copy the value from one pset property to the rest of the selection, this only works to the objects that are in "edit mode" in the pset (using the "copy to selected" ).

In previous version I used (201207), information are transmited with an "paste" icon in pset property, but in later version I don't know how to do it (I only find the previous refered "copy to selected").

Maybe this is the behaviour desired but I think that in a "normal workflow" you need assing pset and properties values to more than one object at the same time. My test are with a blender file with around 1200 objects and try to assign psets and properties to groups of up to 300 objects

M by Moult on 30 Jul 2021 #

@avico the "copy property" feature hasn't been re-implemented, so unfortunately it doesn't exist currently. However, in general you shouldn't need to use it too much, as properties that are set on the object type are automatically inherited by the objects themselves. Do you mind filing a bug here: https://github.com/ifcopenshell/ifcopenshell so that I can keep track of this request and reimplement it?

BlenderBIM Add-on v0.0.210731 has been released with 134 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/

Since the last mammoth release, we've pivoted from developing many new features towards stablising the necessary workflows for native authoring.

Between the last release and now, two presentations were delivered to two international events: BILT 2021 and CAAD Futures 2021. Creating presentations takes time, and a good week was spent to craft an action-packed, information-loaded one hour introduction video presentation to Native IFC. We hope you will enjoy it as much as we enjoyed creating it, and share it for those who know BIM, but not OpenBIM, or those who know IFC, but not Native IFC. You can watch the video here:

New undo and redo support!

Building the ability to track partial changes in IFC, undo, and redo, is no mean feat. Undo might sound like something we take for granted in our applications, but for Native IFC authoring, it's a new world and nothing comes out of the box. After a week and a half of four developers hacking together to solve this, we've finally cracked it. So, feel free to press Ctrl-Z.

Improved stability on native authoring

The last release introduced the new wall and slab authoring tool. Now, we've got a new column, beam, member, and opening authoring tool. These tools are slowly building up in complexity and turning into the toolbox that you expect from any modern BIM application. We've got new parametric profiles, parametric insertion points, and improved project library support. Accompanying this is improved hotkeys and numerous bugfixes and stability improvements on parametric synchronisation. We're not there yet, where we can confidently model parametric objects from scratch in Native IFC, but this set of new tools and fixes gets us closer bit by bit.

Work schedules now cascade

Work schedules are now actually practical for basic scheduling. Dates now auto cascade and recalculate as changes are made throughout tasks in your work schedule. There are now customisable data columns in your task tree and you can sort by any field. Construction animations now support more animation types, including demolition and logistical tasks.

So much more

I'd like a moment of reflection to two years ago where the IfcOpenShell repository had about 50 contributors and the BlenderBIM Add-on did not exist. Today, we have over a hundred contributors and the ecosystem of tools is growing faster than ever before. With all free software, it is powered by you, the community, and you have made what is possible today.

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

What happened to the (actually very smart) Dumb Wall mesh?

Here's a video to demonstrate how to create a wall type, and then change its thickness.

The video's a little old, but you can probably get the concept.

But why get rid of a simple process that works? This seems like multiple extra steps when there was previously something that just worked.

Also, the ability to use Shift-T or clicking Add Type Instance like in this video to turn annotation lines into walls seems to have been removed as well?

And all tooltips are now (undocumented operator) as at 0.0.210801

Ok, it seems to almost work in yesterday's release (0.0.210812), but it fails to get extrusion direction to set a thickness to the plane it creates. and that crashes the process. Tooltips are still (undocumented operator)
