I followed the post, see below, to create a hole through an object. It worked out well but I must have hit some key that I am unaware of. Now, when I zoom out of my 3D space just a little, the object and the grid disappears. When I zoom in closer is reappears but I can’t back away like I normally can. If I hit the top view the object and the light are visible but not the camera and again the same problem if I back away. It’s not a memory issue. I have one object, a square with a hole in it, in 3D space. All I can think is that I hit some key that I would really like to avoid hitting again. Any ideas?
“Add a bezier circle. In edit mode select all then hit the Vkey, this will turn your circle into a square (aligns the handles). Still in edit mode add anothe bezier circle and scale it however you wish within the first bezier circle. Tab back into object mode. Alt+C to convert the curve to mesh. Now you can extrude the region to whatever thickness you want.”
