This is a 3D CAD model of a two-story curtain wall framing system, showing a complete structural layout with vertical mullions, horizontal rails (transoms), anchor brackets, and slab-spanning connections. The assembly demonstrates how curtain walls are anchored at each floor slab while maintaining vertical alignment and modular installation. The highlighted red components represent anchor tracks and structural ties, ensuring proper load transfer and system rigidity across multiple floors. This model is suitable for mid- to high-rise commercial facade systems.
