I've got an assembly with various parts and subassemblies. I'm drawing the different parts in the main assembly so that they are automatically in the right place. Yesterday i was working on one of my parts and my sketches were visible without any issues but then solidworks crashed when i was trying to import a new subassembly. Now that i've restarted it, my sketches are no longer visible, even when i've marked them to be visible. The sketches are visible when i click on them or modify them but then when i exit the sketch they disappear, except for the particular sketch that is selected. I need to use 2 lines made in 2 different sketch to make a reference plane but i cannot select the lines because the sketches aren't visible. Any help would be much appreciated.
