Hello fellow SOLIDWORKS Users,
Please ask your VAR to add your name to the notification list for the SPR#411466 - Feature 'Show hidden components' in assemblies does not work if a selection box is used.
If we get this limitation removed from the software, we will unlock the missing piece from a very good workflow to increase the user efficiency when working with large assemblies. For most of us it will be revolutionary.
So please "vote" on this SPR.
