Sorry for my stupid question but in solidworks I have an assembly of a hundred parts I hide some parts for my design needs Is there a button to make all the hidden pieces appear at once?
If it can help you normally by selecting them, it works (except for me )
If not, in the tree you have a column dedicated to this hidden action. By selecting all your parts by pressing Ctrl and with your mouse you select one of the parts logos, and all your parts are hidden
