We have used Designs Illustrated a few times now to produce 3D visuals to enhance project presentations and have found them to be extremely helpful, quick and have an instant understanding of what we are trying to achieve (working form a very brief sketch!). Wouldn't hesitate to recommend them to any design professionals who are time poor and want to provide the best possible visuals to get the ideas across to the client
