Unigraphics, 1974–2001

Seeing as David Weisberg&#x27;s &quot;History of CAD&quot; is trending today, I submitted &quot;History of Unigraphics&quot; by 3 of the original Unigraphics 7 dwarfs.<p>The article came out at the end of 2024 ... these guys must all be around 80 by now.<p>Edit: Unigraphics X SDRC became the system we know today as Siemens NX

I contracted for an injection molds manufacturer that used Unigraphics from &#x27;06 to &#x27;22 as a general sysadmin. I was &quot;adjacent&quot; to NX and never really interacted with it directly (though I orchestrated a lot of silent deployments &#x2F; upgrades).<p>It was noteworthy to me that they&#x27;d so heavily integrated UG (and customization of UG) into their operations. They started with UG back in the early 80s on a Data General machine. I was told they had proprietary &quot;GRIP&quot; code still in use that dated back to the late 80s.
