Why is the second generation of Simmechanics so hard to learn?

Hello All

I have been working with Simulink generation 1, and things were very clear and easy in first generation! Suddenly the coordinate system assignment to object got completely changed in generation 2 , and the users were left confused on their own to waste time to re-learn everything to to the samething...

What was the point??

What exactly are you refering to with "generation 1" and "generation 2"? What coordinate system assignment?

Link to relevant doc pages?

Simulink generation 2 was MATLAB 5.0, December 1996.

Are you possibly talking about SimMechanics Generation 2, introduced a decade ago in R2012a ? https://blogs.mathworks.com/simulink/2012/11/30/simmechanics-second-generation/

Yes I meant Simmechanics sorry, corrected! now the older versions of MATLAB are taken out of hand, and not put on Mathwoks, and introducing new methods in tools, for no clear reason, will waste milions of hours of time from professionals to re-learn something that already used to work
