I have an assembly with several parts. There are pieces that are not totally constrained. Logically I should move them with my mouse according to the degrees of unconstrained freedom.
There I can't do anything. The room has not moved, and has been since yesterday..... I think it's a configuration problem, but I can't find what.
It all depends on how you made your assembly! In fact it depends on whether you have sub-assemblies or not
If your unstressed parts are in a sub-assembly, they cannot move. To make them mobile, you need to declare your sub-assemblies as "Flexible". (look at the attached image)
In my assembly and among my many pcs, I have another assembly that I had put in flexible. When I remove this flexibility, it unblocks the displacement of the pcs and when I put the assembly back in flexible it blocks the displacement of my pcs....... bizzar bizzar
I don't know if you'll read this post but you should know that the flexible function that I use a lot in large complex ASMs is a very capricious function.
It causes false errors on the constraints (typically Axis and contacts on slide constraints). The only way to restore without touching the constraint and to make a flip flop which consists of going back to rigid and then back to flexible (or the opposite).
And then, miraculously, everything went back to normal.
It's a very practical function but one that I find quite crappy for years (feeling shared by colleagues on another forum).
And this has improved with the 2019 version which better handles large ASMs (they have rewritten part of the code to make better use of the graphics memory).
Kind regards
