I get asked this quite often and I simply explain it is the evolution of lines arcs and circles to objects as components in a 3D architectural design model encompassing the entirety of the the building from design to meta data on performance and materials.Its all about the data..
Autodesk just posted a nice video on YouTube explaining what BIM is.
Happy Throwback Thursday
The video has a highlight from the history of CAD to pioneer Ivan Sutherland with the earliest computer aided design technology Sketchpad. Mr. Sutherland developed Sketchpad in 1963. If you want to know the start of computer graphics for design including you should look into the company Evans and Sutherland and the University of Utah computer science dept. back in the day.We may not have had 3D graphics, the infamous 3D Teapot, Silicon Graphics, and even Adobe owes its founding to this group of graphics pioneers and visionaries.
