# Key Points from #hplusroadmap IRC Discussions

• Participants discussed challenges with the RepRap project's Git repository size (approximately 1GB), which creates accessibility barriers for users with limited bandwidth in developing countries, and debated solutions including nightly builds, Git submodules, or repository restructuring.

• A notable self-assembling solar cell technology was shared that can arrange 64,000 parts in three minutes with a natural self-repair mechanism, described metaphorically as "a jigsaw puzzle that you throw into the air and it comes down completely assembled."

• The community exchanged resources related to open-source 3D modeling tools, particularly OpenCASCADE, an open-source 3D modeling kernel, with links to forums and bug trackers for collaborative development.

• Engineering simulation tools were discussed, including COSMOS software (COSMOSM and COSMOSMotion) for finite element analysis and motion simulation in mechanical design.

• Users shared specialized 3D model collections, including a 3DXML models package and BRL-CAD resources featuring a Soviet HAVOC Helicopter model from the BRL-GSI Paris Air Show.

• A curious industry rivalry was noted between SolidWorks and Autodesk employees editing Wikipedia pages, with a link to documentation of this corporate competition in the CAD software space.
