I used UG products almost every working day for the past 16 years. When I left Delphi last summer, we were using NX3.
UG has been owned by McDonnell-Douglas, GM, EDS, self-owned, and now owned by Siemens.
Here is a
18 minute video showing the latest improvements Siemens has integrated into Unigraphics. I don't know if this is what they are offering in UG NX5 or Solid Edge, or both, but it looks pretty interesting.
(We at AndyMark are beginning a process to evaluate and choose a CAD plaform that serves all of our needs. I have no ties to UG or Solid Edge or Siemens. We will be looking at Inventor, Solid Works, and Solid Edge.)
