edit a .stp file

[Abdi]

hi, I press saying that I am not very good with solidworks, I downloaded an axieme from the internet in .step format (all the components are saved in .step), I would like to be able to edit/view the individual parts, but I can't, when I open a note that says: 'a sketch has been started in the context of this together instead of in one part'.
How can I solve this?
Thank you.

Since you're not good, I'd say that you weren't good either to read the rules, not even to introduce yourself or even to write in the correct section.
if you attach files someone looks at us.

However if it is a together with more party save everything and then change the party. verify if the axieme has all the blocked parts otherwise you have to fix them or bind them otherwise if by mistake you drag something goes all around.

However, the message tells you that you are working together by taking multiple-part references....if it came out in the options you can do it otherwise it gives you as an allert.
