Hello
I want to group all the elements of a subassembly
This is to make this entity easily manipulated graphically
Turning it into a share is not satisfactory because it is irreversible
Merge elements is reversible but not graphically selectable
Is there a trick to "freeze" a subassembly?
Bjr,
Try the Defeature it should meet your expectations.
May the force be with you
Hello
See if it can help you:

Why not put them in a sub-assembly? You will be able to manipulate your subassembly from the assembly as well 
Hello
I didn't know about defeature
it's interesting, it works (except for copying by the graphic selection)
I'm going to use it to group the subassemblies
Thank you and have a good day!
Otherwise, use the speedpack, that's what it's made for (if I understood your need correctly).
Yes in addition this function lightens the ASM so double effect kiss cool.
may the force be with you.
