This article was pretty interesting, especially because it goes way back into history to explain how computation was first used in design, something I had not thought about before. Beginning in Mesopotamia, architects needed to use mathematics and scientific formulas to create buildings that were structurally sound and aesthetically appealing. Research and experimentation with computer aided design occurred in schools, but it didn't take off until the invention of the personal computer. Drafting programs were created early on for macs, but they were limited in the amount of work they could do. After faster processors and printers came out, companies started to develop programs that were suitable for professionals to use. The article points out that the electronics industry has been able to develop software that actually aids in the design process. It knows when you are creating something that is physically not possible and therefore speeds up the design process. Software created for architecture needs to catch up to the other industries to become more efficient.
