![]() So their first CAD software did PCB design. Meadlock was the ceo and had a background in electrical engineering. This is why to this day both Intergraph and Solid Edge are headquartered there. They formed M&S Computing, short for Meadlock and Schansman, in Huntsville Alabama, which is where they were living because that’s where NASA was building its Atlas rockets. In 1969 some of the staff left IBM figuring they could make more money as consultants than as employees - which is true. Meanwhile, NASA had contracted IBM to do calculations for its rockets, because IBM had the mainframe computers. The very first computer system that could draw was developed by Ivan Sutherland at MIT. Someone saw the logical connection between vector math, vector displays, and vector geometry. Some terminals displayed vector graphics, and these were an offshoot of oscilloscopes, which displayed waveforms electronically. Users entered their computing jobs through the terminals, most of which were text only. In those days, you had one central computer, either a big mainframe or a smaller minicomputer, to which tens or hundreds of terminals were attached. Universities and corporations were exploring what was possible with a new technology called computers. Third Strand: Intergraph Now let’s go all the way back to 1960. Cyco launching a revolution by directly reading DWG files.This line of history doesn’t have a Black Swan event, but shows how a logical sequence of events progress to arrive at where we are today. ODA has over one thousand member companies, of which Bricsys is a founding member. They are currently in the midst of reverse-engineering the Revit file format and APIs. He is working at expanding the organization to be the maintainer of many CAD formats. The current president of the ODA is Neil Peterson, and he has a hard-core technical background. The job today is easier as Autodesk apparently spends fewer development dollars on AutoCAD. It took a few years to get into sync, but now ODA members release their CAD software with updated DWG read and write a half-year after Autodesk does. It renamed itself the Open Design Alliance. ![]() We wondered if the ODA would go out of business after this, but it survived that initial event.Ī few years later, the alliance took over maintenance of Microstation’s DGN format from Bentley Systems. He spent most of the alliance’s initial funding on a single full-page ad in the Wall Street Journal, announcing itself and slamming Autodesk. The ODA was initially run by a man who also held a grudge against Autodesk. After IntelliCAD sales failed to impress, Visio spun off its MarComp code to another non-profit organization: it set up the Open DWG Alliance, which had the same structure as the ITC: members contributed their knowledge to improving the DWG read-write API, and license it for their software. Visio realized it needed a DWG read-write library for its Visio and IntelliCAD packages, and so it bought MarComp, one of the independent DWG developers. Now let’s move ahead to Visio and its newly-acquired IntelliCAD program.
