# Summary of #hplusroadmap IRC Log (Sept 12, 2011)

• Discussion of CAD software development focused on file formats, with mentions of STL and STEP file outputs, where STL was noted as more useful for certain applications while STEP files were described as better for SolidWorks integration.

• Technical conversation about a Python-based CAD tool that included components like csg.py, lolcad.py (which generates STEP files), and visualizer.py, with participants discussing syntax choices like "fuse" versus "union" in CSG operations.

• Development work on a Cython wrapper was mentioned, along with patches needed for "esolid" to compile on modern GCC versions, indicating ongoing work on computational geometry tools.

• Brief philosophical critique of an article from H+ Magazine, where someone questioned the assertion that "radical self-interest is an animal trait" that shouldn't be preferred by transhumanists.

• The conversation demonstrated ongoing collaborative development of open-source CAD/modeling tools with a focus on making them compatible with both modern programming environments and established CAD software.
