What is CADD Technology?
How is CADD used in Engineering, Architecture, Urban Design and Planning?
Computer Aided Drafting & Design (CADD) replaced hand drafting for designing in the 1990s. In the past, architects, engineers and master planners drafted their ideas into beautiful plans and renderings. This was a time consuming process; one that did not easily allow for many mistakes or modifications. Older architects reminisce about the times in which they were required to spend 2 hours per day for several months practicing lettering and line weights before they were allowed to touch an actual set of plans.
Today, we can watch a video which flies through a future building or master plan before it has even been constructed. Almost like a movie, it allows us to experience the transformation of our world. Citizens can participate in the planning and design process more actively.
It shows us how our environment accommodates social, environmental and economic transactions. We can predict the way water will move from one point to another. There are methods to show us where a building is losing heat. CADD allows us to incorporate more information and data (for example, traffic, weather patterns and sun radiation) to build more effectively thus reducing waste and cost. In addition, you can simultaneously integrate various disciplines together which makes it faster and easier to modify the design and/ or fix mistakes, all by a simple click of a button.
CADD technology allows for the study of terrain, data, patterns and processes in various scales: a small house, city block, neighborhood, city proper and region. We can simulate different scenarios at larger scales within a shorter period of time. Clients can receive a PDF of their design plan on their smart phone and send their comments as fast as they received it. The art of manually drawing plans will soon become a memory for too many, and a non-existent skill for others.
CADD enables us to keep up with the large amounts of data that is available on the internet and to build intelligent buildings- responsive to the people inhabiting them as well as giving back to the environment. It is a fast-paced world, with a fast moving mouse!
