Worked at refactoring the application. Inserted the modeling manager module that handles the 3d/2d modeling modules, inserted the layout module with the tree view on left and the drawing area on right, improved the working flow. The modules seems to fit properly and worked well. Two more hours are needed to fit properly also the Sketcher and finish the toolbar hiding showing mechanism. Planning to finish this tomorrow and insert also the OCAF functionality.
It will be difficult to finish in time the 0.0.1 release but will try to keep the schedule.
