Adding edges with Quickslice

- [Narrator] To prepare for a Boolean operation, such as a subtraction, we need to make sure that the objects we're working with, or the operands, are legal for Booleans. And what does that mean exactly? Well, a legal object is one which has a so-called manifold topology that can be laid out flat. If all the edges were cut apart, it could be laid out flat. There would be ability to fold it back up the way it was. That's what's meant by manifold. Another requirement for Booleans is that we have no concave polygons, or polygons with holes in them. This object here currently had really no detail. It would not work if we tried to do a Boolean subtraction with two of these boxes. We would get unpredictable results. To prevent that from happening, we can cut a new edge here, or an edge loop, right down the middle. That will split the object into two large polygons in the front and two in back. That would help the Boolean operation so that it would not have an concave or weird polygons…
