The document describes a 3D building application created by students Omer Akram and Usman Shouket under the supervision of Mr. Ammar Rafiq and Ms. Adan Iqbal. The objective of the application is to allow constructors and architects to design 2D models by dragging and dropping objects, which will then automatically generate a 3D model. The application uses tools like Android Studio, Photoshop, Unity 3D and 3ds Max to import 2D objects, develop 2D models, convert them to 3D, and provide login and feedback features. So far the project has completed requirement gathering, planning, design, and implemented login and basic 2D/3D functionality.
