rescue of complex assemblies

[gtsolid]

Good morning.
working on a big group I have problems saving the situation after hanging various parts.
that is all the screws and similar details, that I do not need.
After saving, closing and reopening, I find myself many of these components in their place.
Can you tell me something?

have you created a configuration?
are toolbox elements?
many=all? Someone's not?
always the same or random?
subaxis or main level?

I solved by opening up various sub-axis (some nested in others) and suspending from there what I didn't need

could, hypotheses based on vague reminiscences, depend on the fact that some subaximes were completely or partially light weight.
