FreeCAD Test File

http://img.youtube.com/vi/kCk6uS-fRUY/default.jpg OSE Developer Test Video

How many hours each part of the test took to complete:

1) Installing Linux: ~3h. Tried to do a full install onto USB stick but display wouldn't work.

2) Learning FreeCAD: 4h

3) Documenting your work: 2h

Learning FreeCAD was the most difficult task.

Other feedback: A sample FreeCAD file with a competed cube would be helpful as a reference.

Score: 100% of test points completed.
