Vectorization is the process of converting raster images into vector graphics, which can be edited and scaled without losing quality. Architects need vectorization for several reasons. Firstly, vectorization enables architects to digitize hand-drawn sketches, enabling them to edit and refine the design using computer-aided design (CAD) software. This saves time and resources, and improves accuracy and consistency in the design process. Secondly, vectorization allows architects to create vector-based drawings for presentations, proposals, and marketing materials, improving the visual quality and impact of their work. Finally, vectorization enables architects to create accurate and detailed plans for construction, including floor plans, elevations, and sections, which can be easily modified and updated as the project progresses. Overall, vectorization is an essential tool for architects, enabling them to create, edit, and present their designs more efficiently and effectively.
