# Key Points from #hplusroadmap IRC Discussion

• NanoEngineer-1, described as "the world's first nanomechanical modeling software," was a major topic of discussion, having received $3.5M in funding over 4 years before its development team disbanded. The software can model from single atoms to structures with 10 million atoms.

• The software will transition from a private CVS repository to Git, suggesting a move toward more open development, with its current version available for download at a shared link.

• Participants compared 3D printers, specifically the BotMill Mendel ($1545 assembled) versus Makerbot, noting the Reprap Mendel's larger build area and apparently superior engineering quality.

• A debate emerged on the practical utility of 3D printing versus CNC milling, with one user describing 3D printing as "not much more than a toy at this point," while acknowledging its potential for complex parts where traditional milling would waste significant material.

• Michael Moore's work with NanoEngineer-1 was highlighted, focusing on the practical potential of DNA-based designs versus theoretical molecular manufacturing applications.

• Upcoming research papers by Freitas, Merkle, and Allis on "Single-Atom Radical-Exchange Mechanosynthetic Transfer Reactions" were mentioned, covering elements from periods 1-4 using adamantane tools.

• A user reported successfully implementing a feature in HeeksPython (CAD software) that enables scripting the addition of cylinders in any orientation, after resolving C++ pointer issues.
