until now I used the part family function without problem but since today when I edit the part family I can enter values but as soon as I want to come out, SW blocks I can't do anything except Ctrl+Alt+Delete.
I noticed this morning that a part had lost the part family function, i.e., I still had the old configurations but I couldn't edit it anymore because it had disappeared.
I did a test with a new part and a part family insert but I get the same result.
For solidworks not to my knowledge and for excel difficult to say in addition I just noticed that excel is in automatic download and installation and I am not a fan of automatic installation.
In the case of an update, would there be a procedure for it to work again?
You would have to check and note the version of the programs, try to restore with the internet connection disabled so that you can then open Excel and disable automatic updates, and check if the version numbers have changed. Then try the part family change again.
At the time for me, I should have specified "[...] mark the subject as resolved by checking the message that contains the solution to the problem". Thank you.
