I have encoutnered an issue that I never had before.
the assembly file i downloaded from my supplier
no matter it comes as a .step/.asm
none of the components can be moved or mate
solidworks is telling me that all components are fixed
but there is no mate exists in the assembly
on the left tree, all components has a (f)
cant get rid of them.
does any one know how to solve this problem?
at the moment,
i have to put everything together by hand
a bit time consuming
