Mates are hidden

Hello guys,

as you know in the last versions of solidworks i mean under 2017 , we had access to the mates of the sub-assemblies and the sub-parts, i mean we didnt have to open the sub-assembly and edit or something els.

But now in 2017 it looks that it's been limited and the access is caught through the Opening the file or setting as set to resolved and it's awful by the huge size of the assemblies to set to resolved than set as lightweight.

Is there any option in order to active this abbility?

thanks all

Mohsen
