Sometimes you may want to change only part of a wall instead of the entire wall. For example, you might want half of the wall to be brick and the other half to be painted drywall. To do this, you first need to split the wall into separate sections. This is where the Wall Break tool is useful.

To use it, go to the Floor tab in the main toolbar and select the Wall Break tool. Then click directly on the wall at the point where you want to divide it. The wall will be split into two separate wall segments.

Once the wall is divided, you can click on each section and apply different materials, heights, or other properties. For example, you could make one section shorter to create a half-wall, or change the material on one part without affecting the rest of the wall. This gives you more control and flexibility in your design.
