Some faces not showing in modelling, but visible in sculpting mode I'm pretty new to blender. I was working on a model, and after some accidental key typing, I can only see some faces of my model in modelling mode, however, in layout and any mode that won't clearly show vertices, I have no problem seeing the faces. here are some pictures to illustrate
Hope you can help me and thank you.
It looks like you have accidentally deleted edges &amp; faces (X then Only Edges and Faces).  If that's the case you need to undo or go back to an earlier backup.
But just to make sure, I suggest pressing Alt + H (Reveal Hidden) in edit mode first.
