command insert + ctrl

[Esselle]

Good morning, I have a new pc and match a difference after installing solidworks.
I was used to insert within the assemblies, more particular at the same time with this procedure: selection of details and moving inside the window holding lazy ctrl.
before the new installation, the constraints between the details of new insertion were also preserved, now no longer, do you know how to set?

selection of details from where?
from the window insert part?
from the feature manager (then it is a copy and not insert)
drag&drop from windows explorer?
more.. .

from the feature manager, it is actually a copy, I expressed badly.
