simplify third-party step files

[Giancesa]

it happens that sometimes amount file step of vendors that however have complex files and I would like to simplify, leaving only the external parts. as you can delete the parts that I don't want. everything is to lighten files. Thank you.

multibody or together?

 

[Giancesa]

What do I want? I wonder why when I used inventor, whether it was multi-circums that together gave me the chance to cancel. Now I opened an old file created by my colleague, which contains a multibody step, but I can't erase any body.

Mine was a question, not a suggestion.
if the opening of the step returns you a set you have certain possibilities, if you return a multibody you have others, if you return a part with a unique body (e.g. a motor) the possibilities are reduced, but there are.

Now I opened an old file created by my colleague, which contains a multibody step, but I can't erase any body.

said so does not help to understand. you have to imagine why you can't erase a body and it's not easy.
a multibody has, in the feature manager, a folder with the list of bodies; you can also create a separate cut if you want to have a little more control. in any case with the delete body function you can maintain or eliminate the desired bodies.
the heaviness of the files is given marginally by the amount of the bodies, the critical point is the geometry of the bodies; It is better to have a file with one hundred simple bodies rather than one with 5 bodies with real threads and girdles, written, splines, dozens of fittings and bevels.. .

if you attach an image or still a file you understand what you are talking about

I think, but I'm not sure... that everything depends on who export the step file.
there are various settings that many do not consider.
But it's a talk about my software.

in my opinion I would say no because a file with complex geometry such as a complete engine of vines on the plate with embossed writing, fully radiated fins, power wires (I assure you that they find it) has an undeniably processing that it is a set, a multibody or a single body. change the method to clean it up.
If then you mean that those who export should do so by including only relevant geometry I think it is a complex speech that must include multiple factors.
a step is an exchange file that you do not know, almost never, with what program is exported and you do not know, practically never, with what program is opened. and each program has its own settings

You can't do anything because you opened the step with active 3dinterconnect.
open the step by turning it off and you can mess up the files as much as you want.

perfect, thank you
