Why should they? They had very little or zero interest in the product when they acquired it, so why would they be interested in promoting it or Alibre LLC now????! If 3DSystems are in the same state they were when they had Geomagic Design, then they have enough problems of their own to worry about!
Which ones? Before I retired I'd see an occasional review article in one of the trade mags at work, but it's been a while and it was only after a major release of AD.
IDK random ads in random news articles. I imagine my use of the Alibre site or my Google searches for CAD related things is used to target ads at me.
