I am unable to locate where the engineering references/books that were present in Mathcad 15 now in Mathcad Prime 8.0. Can someone point me in the right direction? Does my company need to add this as a service?
I may be wrong but I fear that the answer which was given here also applies to Prime
It does apply to Prime.
Roark's was available as an additional purchase through the PTC eStore until the end of December 2021 when it was end-of-saled.
The web-based "library" Knovel used to have Roark, Hicks, and other engineering handbooks that had Mathcad 15 files embedded. Whether those still are available and how well Prime 8.0 would translate them is a good question.
I had Roarks as an e-book. Whoever made those files loved global variables and didn't like functions--most of the graphs were plotted from vectors. Made design calculations challenging.
Roark seems not to be available (any more) at Knovel, Peterson a.o. are (not sure if Mathcad/Prime based, though).
Might have been "improved"!
Its very sad but fully understandable (given the 'development' of Mathcad/Prime) that switching from Mathcad to Matlab has to be seen as an improvement.
