Google Code-In Task for BRL-CAD

My first task in Google Code In was to download and launch the BRL-CAD program and then draw something. Installation was quick and efficient, no problems (version for non-coders). The task was to draw something from various programs (specifically, Archer). It is located in the bin file as the archer.exe file. After clicking, the program will start. However, behind him I could draw anything, I had to learn how the interface works. The tabbed tab is clear, so I quickly understood what is going on and how to use the tools.
