Before computers there were hands and tools. Before hands and tools there were just hands. Humans have always been designing and throughout human history drafting is what became of it. With new technology in building during the earlier years drafting needed to be changed to accommodate it. Humans have always been able to find better ways to accomplish things. Drafting is no different.

Before people used tools to draw something they went to what we call now a “General Contractor” with an idea and he had to come up with the rest. After a while the contractors wanted more. Just an idea wasn’t enough for them. Their clients sometimes wouldn’t like what they had built for them. So eventually the contractors asked the clients to tell them exactly what they wanted. Since it was hard to sketch accurately, tools were developed to aid them in drawing. This enabled the client to show the contractor exactly what he wanted.

As the population grew rapidly the demands for faster and more accurate plans did also. Once again drafters looked for a new way to draw. They decided to turn to the computer. In the 1950s MIT discovered the capability to display a computer-generated image on the screen (Zandi, 5). Up until

(Goetsch, 26) Any time the user edits that object the change that he or she made is updated in all other views as well. (Bethune, 71)) Once an object has been drawn in 3-D mode a user can at any time look at it from any angle (Bethune, 74)) or create a cross section of that object.

There are many different programs to draw a sketch on. Other programs animate a building or object so one may simulate what happens with the building. It has changed the way people go about their drawing and designing process. The accuracy also has enabled us to create smaller and faster computers allowing us to advance in CADD capabilities and then advances more on the computer. But on the other hand if his drawing are neat and accurate then the client can tell that he does take pride in his work and he likes what he does for a living. (Grad, 46)

One thing that CADD has influenced is the process that architects go through when they are designing a building something. The touch pad however can be bought to the size of the screen. Before a house is built we examine the building in a 3-D program that tells us where a leak is.

Once the sketch has been made the actual measurements need to be thought of. Without CADD we would never have been able to design the engine or even the body of the cars out now. (Grad, 44) The simulation technology has advanced so much that architects can study energy loss and subtle inefficient performance by completing buildings in 3-D long before constructio!

n begins. If a client doesn’t think that their drafter likes what he does then they probably won’t hire him. With the 3-D capabilities we are able to design them how they would look from any angle.
