Is it possible to take the parts already on the design plate and lock them so rise and run on other parts do not affect the dimensions of attached parts already good to go? So just a lock and unlock feature maybe using the same operation as creating a sub-assembly, just have a blue button for lock/unlock where those parts are simple temporarily non-editable.

That would be great for designs with shells and then parts over the shell. :) If possible thank you very much! I know people ask a lot, I am just extremely involved lol. .
