I am doing a school project and I zoomed out to far and panned to far and I cannot locate my house! This is my screen. Help!
Have you tried clicking the "Home" view button above the view cube? You need to move the mouse over the view cube to see it, it looks like a house.
Click the node next to the bodies folder. Are the lightbulbs on for all bodies?
Try the same for Sketches. These should be 'off', but when you turn them on, they should show where bodies are (unless you've moved the bodies after making them).
One more thing, go to Options and try some of the display options, like Shaded, or Wireframe.
