Hi everybody,
after about 2 month of hard work, here is my application latest release.

Here is a brief of what is new:

0.7.5.2 - Changes to previous version (2012.10.23)

Added
- New DrawBrickMode allows you select a brick from toolbox by simply drawing its shape
Refer to the following video for detailed instruction on how to use it
- Additional parts patches available separately on download page

Fixed
- Better part positioning when using Alternative UI (really recommended now)
- A lot of changes and fixes in hinges managements. Now the 8258 robotic arm is working !!
- Racks movevent are sometimes along a wrong direction
- Instruction Miner does not always shows all controls
- Occasionally selecting hidden grouped parts causes application crash
- Using State Buttons in Animation console cause application crash when loading a saved model

Changed
- Updated available part library
- Selecting parts should now be a bit faster due to code optimization

I need some feedback about DrawBrickMode. Please let me know...
