So I had a prob. like this before and I tried a bunch of different things and I still can't get it to work. Last night I was modeling all night and when I was done for the night I saved all my work and closed out Maya. Today, I just opened up my project and it turns out that nothing is showing up in my main views. If I hit the space bar I get the 4 views to show with all my work and the grid but, when I select a specific view to work in, there is nothing showing up. I tried hitting the "F" key and nothing still showed up. I don't understand why everything was fine last night and now today everything is all messed up. Can someone please direct me to what I have to do to get my views working properly?
