I don't know how this happened, but suddenly, my OGL object outlines (in object mode) are now gone. This makes it difficult to see object edges when they are placed adjacent to other objects. I need the object mode outlines back, but HOW?
Enable wire to see the black edge outlines regardless of selection. Enable "Draw All Edges" to display all edges, whether coplanar or not. By default, coplanar edges are not drawn.
