# Key Points from IRC Discussion

• Developers discussed CAD software options, comparing NaroCAD (.NET-based with Windows limitations), HeeksCAD, OpenCascade (OCC), and Wildcat-CAD, with particular focus on cross-platform compatibility issues and the excessive complexity of OCC that made developers wish for a streamlined version.

• The SKDB (Simple Knowledge Database) project was actively developed, with participants working on Python implementations for assembly graphs, volume collision detection, and integration with OpenCascade for 3D modeling functionality.

• Augmented Reality discussions centered on display technology limitations, contrasting full headset designs with more discrete solutions like OLED displays integrated into eyeglasses combined with IR eye-tracking systems.

• A developer shared progress on designing a printable stepper motor, including detailed considerations of gear profiles (involute vs. cycloidal) and concerns about wear rates in 3D printed mechanical components.

• Participants explored CAD model creation workflows using Python scripting to generate curves, with subsequent processing through Inkscape (saving as SVG) and importing to HeeksCAD for extrusion into 3D models.

• Military technology discussions covered tank vulnerabilities, EMP countermeasures, and the philosophical concept that "for every high tech threat there is a low tech solution."

• A method for accessing normally restricted ANSI standards documents was discovered and shared, involving manipulation of URL parameters on the ANSI website to download PDFs.
