Native #IFC authoring with #free software you ask?
Check out this short video - a highlight from our recent webinar.

Great news for #BlenderBIM users!
You can now tap into the buildingSMART Data Dictionary (#bSDD) directly from #BlenderBIM.

The @FreeCADNews Project Association has a grant program for developers, but they want to improve it. So they asked me to research best practices and come up with actionable recommendations. That research is now public

In @Cogito project, we use openBIM (#ifc, #ids) to prepare BIM models for #digitaltwinning #construction projects (delivery phase). This article covers our data ingestion and shows how we make great use of @OSArchOrg's @BlenderBIM

@DLabz @FreyaHolmer IFC / standardization might not be the best place for these kind of innovations though. It is the shared common denominator between implementations, a bit orthogonal to something novel. This sounds more like research paper or prototypical implementation to influence the sector.
English
@aothms @FreyaHolmer No, not NURBS. Think more like Phong Shading.
It’s intended as an unified interface of defining curves, lines, polygons, triangles and curved triangles (IfcAdvancedFace).
It also sidesteps the inherent clumsiness of triangulating a NURBS surface.
I’ll explore this further …

@aothms How about this idea as a foundation of the IFC geometry kernel?
One unified expression of all curved lines and surfaces. Covers rational cases. Avoids Cox-deBoor loop. Scales to higher dimensions. Seems at least G4 continuous…
@FreyaHolmer am I missing something?

@BiMvoice The last two recently got deprecated in favour of conventional psets ifc43-docs.standards.buildingsmart.org/IFC/RELEASE/IF… That's 4.3.2.0 only though

🎓 I've created a new educational platform.
🎥 The platform currently gathers the free courses I teach on Youtube , about IfcOpenshell and BlenderBIM
💼Paid Courses with student support are also coming soon!

Honoured and excited to receive this grant for further integration of BIM and GIS visualization
Interoperability and long-term data usage are recurring themes in my work. This grant supports next steps for a powerful @CesiumJS + ifcopenshell integration!

Yes. Go #OpenBIM. Go #OpenSource. Did you know that #FreeSoftware #IfcOpenShell can create geometry trees? A geometry tree lets you efficiently select objects by XYZ coordinates or bounding boxes. Read more here blenderbim.org/docs-python/if…

Yes. Go #OpenBIM. Go #OpenSource. Did you know that the #FreeSoftware #IfcOpenShell lets you either import, export, change version, or reserialise IFC data to dozens of formats? Work with #NativeIFC through #JSON, #DataFrames, #SQLite, and more.

The number of monthly unique contributors to github.com/IfcOpenShell/I… keeps increasing. Join in on the fun! Let's aim for a new record for June 2023.

@BlenderBIM We're still struggling with good UX. We're now a bit in between of paginated list (with search and filtering later) or a tree. Thanks for the feedback :)
English
@aothms BTW I might recommend grouping by entity class (1st level grouping) and message (2nd level) which makes this a lot easier to digest for large files with thousands of validation errors.

validate.buildingsmart.org just received a major update
Validates your models wrt:
- syntax
- schema (incl where rules and functions)
- additional rules
- consistency with bsdd
Valid and reliable data is the cornerstone of our industry.
