• The SKDB project is building an open-source CAD/CAM toolchain that now integrates LEGO assemblies: new Python modules (`legos.py`, `occ-pyldraw.py`) couple the OpenCASCADE geometry kernel with the LDraw part library and the PyMates constraint engine to enable interactive 3-D visualization and automatic collision-checked mating of bricks.

• A generalized mating algorithm is under development that, after each mate is applied, iteratively scans every brick to mark interfaces as aligned (mated) or occluded (collision) and catches `CollisionError` exceptions, aiming to automate the assembly of complex multi-part LEGO structures.

• Participants surveyed the broader open-source CAD/CAM ecosystem, evaluating GPL tools such as HeeksCAD, PyCAM, Salome, and BRL-CAD for parametric design and CNC tool-path generation, and identified gaps in documentation and interoperability that hinder wider adoption.

• A Lego-as-CAD experiment was prototyped that converts LDraw .DAT part libraries to Wavefront .OBJ via LdrDat2Obj, then onward to OpenCASCADE for solid modeling; test files and batch-conversion scripts were posted at http://adl.serveftp.org/lab/legos/.

• Performance bottlenecks in PythonOCC were discussed, particularly the unusably slow STL mesh import; the group proposed replacing the default importer with StlMesh_MeshExplorer plus BRepBuilderAPI_MakePolygon and noted the absence of the faster XSDRAWSTLVRML module in PythonOCC.

• A digitization effort is underway to OCR key manufacturing-process texts such as “Fundamental Principles of Manufacturing Processes” and “Manufacturing Processes Reference Guide” at roughly one page every 1.2 minutes, with cleaned PDFs to be hosted on adl.serveftp.org.

• The community debated how to reduce the expert labor required to encode lab protocols, suggesting automated validation tools and a strict separation of executable code from declarative data as possible mitigations.

• Neuroscience discussion referenced an fMRI study locating the “central bottleneck” of dual-task interference in posterior lateral prefrontal and superior medial frontal cortices, framing it as a hardware limit on human multitasking and decision-making.
