- A proposal was floated to build “AtomCAD” (an atomic-level CAD tool) on top of the open-source boundary-representation (B-rep) kernel Fornjot so users can model nanostructures with conventional solid-modeling workflows.  
- Fornjot (https://www.fornjot.app/) was highlighted as a Rust-based 3-D modeling library that can be embedded as a dependency, potentially giving AtomCAD industrial-grade geometry handling without re-implementing B-rep math.  
- The term “BREP” was briefly confused with the bioinformatics tool “BrEPS” (enzyme-specific sequence profiles), prompting clarification that the intended meaning was Boundary Representation for 3-D solids.  
- Orion’s Arm, the long-running hard-science transhumanist world-building project, was noted to still be online and active on Discord, contrary to rumors of its demise.
