Bonsai release artwork showing a rabbit with the Bonsai logo

Bonsai 0.9.0 released

Bonsai 0.9.0 has been released with 2,070 new features and fixes. The free software BIM authoring tool gains a redesigned IfcOpenShell engine: the release team’s fourteen-model benchmark reports IFC opening 2.5–3.4 times faster, with less than half the memory used by 0.8.5. ...

CADBase web viewer displaying a 3D IFC bridge model with file revision history

CADBase Brings Version Control to FreeCAD and Blender

CADBase is an open-source data exchange platform designed to streamline collaboration among teams using different open-source design tools. Operating as a centralized infrastructure, it provides engineering-tailored version control and fills a gap for workflows utilizing both FreeCAD and Blender. Through native library add-ons, the platform lets users store, track, and share 3D models and manufacturing data across a project lifecycle, eliminating messy shared folders and untracked file iterations. ...

CAD Importer window in Unity showing mesh, level of detail, physics, and FreeCAD conversion settings

CAD Importer brings CAD and BIM models into Unity

CAD Importer is an MIT-licensed Unity package for bringing CAD and BIM models into real-time robotics simulations and digital twins. Written in pure C# without native plugins, it supports editor imports for STL, PLY, OBJ, glTF and GLB as well as STEP, IGES, and IFC, with asynchronous runtime loading available for the mesh formats. ...

LibreCAD interface

LibreCAD now runs in the browser through a WebAssembly port

Magik has published LibreCAD in your browser, a WebAssembly port that runs the full GPL-licensed LibreCAD desktop application in a browser tab rather than a reduced viewer or JavaScript reimplementation. The demo loads the C++ and Qt application through Emscripten and Qt for WebAssembly, with the fork available as LibreCAD-Web. ...

TGraph diagram showing TopologicPy graph entities and relationships

TGraph gives TopologicPy a more explicit graph layer

Wassim Jabi has published an introduction to TGraph, describing it as a more explicit and efficient graph representation for TopologicPy. TopologicPy is an open source Python library for spatial modelling and analysis in architecture, engineering, and construction. Its graph-based representation is used to connect geometry, topology, information, graph databases, knowledge graphs, GraphRAG workflows, and graph machine learning. A clearer graph layer is therefore relevant for workflows that need to reason about spaces, adjacency, connectivity, and semantic relationships rather than only geometric shape. ...

IFClite.dll wiring Rhino, Grasshopper, and Revit to an IFC file in-process while an IT security dashboard stays quiet

IFClite gets a native DLL for in-process IFC parsing in Rhino, Grasshopper, and Revit

IFClite merged PR #1182, a contribution from Mathias Sønderskov Schaltz that lets IFClite parse IFC inside the CAD process — as a plain DLL. The clean way to call a Rust engine from Grasshopper or Revit used to mean running a local server and talking to it over HTTP. But the moment something opens a port on a managed machine, enterprise IT lights up: firewall rules, security reviews, the whole dance. The FFI wires IFClite straight into the process instead. A new ifc-lite-ffi crate builds with crate-type = ["cdylib"] to ifc_lite_ffi.dll, and the host loads it like any other library. No server. No port. No network. Just a function call. ...
