Sketches can range from hand or CAD drawn sketches to help convey an idea or they can be more detailed to assist with visualisation and birds eye view plans. Sketches can be elevation, perspective or isometric drawings that help to give depth to CAD plans as well as encourage new and inspirational ideas. All CAD Concept Drawings on the other hand, come with some form of  perspective or Isometric sketch to help convey the ideas. Each project is different and there are No "One Size Fits All" plans. Angelique can help you with what will suit you best for your budget needs and desires, especially if you want to implement your own DIY project.
