I would like to know if anyone would be interested in a generic CAD application framework. The framework provides basic services common to all CAD applications:

-- GUI
-- Viewports
-- Editable Graphics View Elements
-- Graphics System
-- Model-view architecture
-- Generic document model
-- Standard tools such as Save/Load/Undo/Redo/Copy/Paste/...etc.

The system is extensible (vs. customizable) through plugins. The project is still in-development, and screenshots are coming soon. I'm open to features, suggestions, and use-cases if possible.
