Hope so this video Helpfull for all
I think this happens because your parts are as light mode loaded. Your parts are not "completely" loaded because the assembly is huge (I suppose). If you open the parts where you need the sketch, then will this part completely loaded and you will see the sketch in assembly too.
Hello. I have the same problem as d8224b28 and even though I made all parts as resolved, I still cannot display sketches. The icon to view sketches in the menus is greyed, and no possibility of activating it. How can I solve that? Thank you.
you must go in the menu View/Hide All Types, click on the "Hide All Types" field, that will activate enable the viewing icons.
