Computer-aided design (CAD) software has become a popular and integral tool for interior designers. CAD software allows designers to visualize and experiment with their design ideas in virtual 3D environments. It provides thousands of furniture, color, texture and design options to create realistic digital representations of proposed interior spaces. The software saves designers and clients time and money, while allowing previously impossible design possibilities to be explored. CAD has complemented traditional design methods and made the work of interior designers much more efficient.
