Direct modeling CAD systems (SketchUp) can be made more precise and predictable by adding some facility for parameterization, this technique is called: Variational Direct Modeling
http://www.ledas.com/pdf/VariationalDirectModeling.pdf
For an even broader overview of why variational direct modeling is a way forward: [http://isicad.net/articles.php?article_num=14805 Direct Modeling - Who and Why Needs It? A Review of Competitive Technologies]
A potential open source direct modeling CAD application should have this feature.

Researching the implementation of an Operational Transform web based CAD system.
Purchased a copy of this paper: [http://dl.acm.org/citation.cfm?id=2145412&CFID=529177936&CFTOKEN=14543251 Operational transformation for dependency conflict resolution in real-time collaborative 3D design systems]
Which discusses a few specific OT functions necessary to deal with graphs of dependent objects, essentially this resolves some issues related to multiple people editing inter-dependent parametric data at the same time and how to merge conflicting operations.

  • Made a lot of progress on OSEDev Workbench. Using websocket-client library without the QtNetwork stuff seems to work pretty well.
  • Qt Designer is pretty nice, I have a Login dialog and the chat window done with Qt Designer and then integrated with Python.

  • Really digging into Duniter over last couple of weeks and thinking about how it can work for OSE Coin. There are some issues with the currency related to growth. Started a thread on duniter forum to understand feasibility and options.
  • Working on OSEDev Workbench:
    • PySide does not expose QtWebSocket (unlike PyQt, which does have this). This will make it a bit harder to integrate the workbench with osedev.org. Will look into hacking the pure Python websocket-client implementation to accept the PySide QtNetwork ssl socket object.
    • Will have to split up all of the tasks needed to get osedev and the workbench talking to each other into bite size chunks so I don't get overwhelmed.

Worked some more on the GT2 double pulley trying to get the belt and teeth done. Josh helped me out a lot with answering questions, etc.

I think the main issue is that I was using FreeCAD 0.17 (daily build) and it's just too buggy. Going to continue later with 0.16 and see if it's a smoother experience.

Wrote a little bit of Python code for Michel to help him with his blender part exploder.
