3D technology solves 4500 year old riddle: Great Pyramid was built from inside out

April 12, 2007 Dassault Systèmes’ in conjunction with researcher Jean-Pierre Houdin, have used cutting edge 3D technology to solve a 4500 year old riddle – how the Great Pyramid of Giza was constructed within 20 years and without wheels, pulleys or iron tools. The pyramid is the oldest and last remaining wonder of the ancient world, and is as much famous for the alternative, often supernatural explanations offered for its construction as it is for its historical significance. Houdin used CATIA 3D software to digitally create his hypothesis, which theorized an “inside out” construction process. The highly advanced software was able to take into account the strength and resistance of the materials used, the ability of workers using primitive tools to move the blocks into place, the effect of aging, and even the effect of the weight of the pyramid on the pyramid itself. You can see the work in three dimensions here.
