# Summary of #hplusroadmap IRC Log (September 12, 2009)

* Bryan (kanzure) worked on surface model reconstruction code that converts point clouds to 3D CAD models, with the goal of replacing problematic STL files with proper boundary representation models.

* OpenCASCADE development was discussed, including challenges with its API, class structure (TColgp_Array classes), and the discovery of a Python/Jython scripting interface for OCC 1.3.

* A community member shared detailed hackerspace design plans featuring specialized areas for machining, electronics, photolithography, presentation space, and data servers, with discussions about accessibility features and structural requirements.

* Participants discussed infrastructure considerations for hackerspaces, including reconfigurable walls, proper concrete thickness (12 inches recommended) to reduce vibration for precision equipment, and alternative energy sources.

* Welding processes, equipment and safety standards were researched, with links shared to resources about different welding techniques and proper protective equipment.
