In collaboration with the Historic American Engineering Record (HAER), a partnership established in 1969 among the National Park Service, the American Society of Civil Engineers, and the Library of Congress, CAD vendor Autodesk is participating in an effort to document the key historic sites and structures that depict America’s greatest engineering and industrial achievements.
The sole purpose of HAER is to create a permanent documentary record of the country’s engineering and industrial legacy, including bridges, major ships, railroads, canals, even classic buildings like steam-powered lumber mills and hallmarks like San Francisco’s Golden Gate Bridge.

What Autodesk brings to the project is its 3D tools, particularly its AutoCAD design package and its work with partners around 3D point clouds. 3D point clouds refer to a set of vertices in a three-dimensional coordinate system, which are typically used to represent the external surface of an object. Autodesk is leveraging 3D laser scanning technology from Leica Geosystems and software from its development partner, kubit, to help HAER capture point clouds of data to create a 3D image of the renowned sites.
HAER is calling on AutoCAD’s point-cloud rendering engine and kubit’s software, which transforms the point cloud data into something AutoCAD’s 2D and 3D modeling engines can understand. Once a 3D model and 2D drawing of the historic site or structure is created, the documentation is housed in the Library of Congress for access by the general public, ensuring that future generations have a window into the country’s industrial achievements.
Autodesk’s collaboration is one of many similar point cloud efforts underway to archive culture heritage sites and structures around the globe. One of the more prominent organizations engaged in this is CyArk, a non-profit that employs laser scanning and digital modeling, among other technologies, to digitally preserve cultural landmarks -- everything from the Mount Rushmore National Memorial to Pompeii and the Piazza del Duomo in Pisa, Italy.
That's a good question, Chuck. I don't think officially this is a project that is open to anyone who wants to access the point clouds to recreate historical buildings and sites. I think this is just Autodesk working with this historical entity and other partners to do so. That said, there is Autodesk point cloud technology accessible to mainstream folks called Project Photofly. I believe it's currently still an Autodesk Labs project, but downloadable for beta. That is the same technology being used on this project.
Beth, I agreed. History and historical things are nation’s assets. So it’s important to preserve and keep it for the coming generations. I hope the 3D vision can help for a better realistic vision and a walk through experience.
Beth, are we talking about the ability for anyone to gain access to these 3D point clouds and then being able to build models with their own 3D printers?
It is really cool. And using technology like point clouds, 3D modeling software, and 3D printers to recreate history or to pull together historical documents, items, artifacts in a compelling way so it really tells the story is only going to make the past far more accessible to future audiences.
Beth, this is really good news. I recently happened upon a repository of source documents from the computer industry going back to the 1940s. It is really revealing and interesting to see what people were doing and thinking then in a filed that is so important. The same is true of the things we build. The last century or so has seen some of the most fantastic developments in this area and they should be preserved. We often do not pay much attention to recent history.

For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
