function saves bodies eliminations some doubles

[Sp4rk0]

hi to everyone, I searched on the forum something about the function saves bodies, but I saw that to nobody from the problem that I have.
I practically have a frame made of various traversines, I have to pull out all the steps of the traversines so as to send them to the laser cut, when I do insert - function - saves bodies putting the jug on drifts parts resulting from the similar bodies, on the final axieme 1 or 2 travarsini disappear, say that 95% goes to good end but some are just eliminated from the final axieme.
If instead I create the axieme without that check out the traversins there are all, but obviously I find 5 equal parts with 5 different names, am I wrong something I or is it something that happens frequently?
Thank you.

Can't you find them in the axieme or are they not really saved?
Are they unique bodies or are they part of a group?

I start from a par file made with the welding package, I create a frame of multiple structural elements, then to create the various tubes to be sent to the laser cut use insert - functions - save bodies, in this way it makes me create and save an asm file and all the structural elements are converted into par singles, if I create them with the tick on derivatives parts resulting from the similar bodies, some double bodies are not put in the same assem, it creates me without the tick are put in the axieme but of course I am not with 5 types of pipe but with 100 all different.
