Combining Zones

Combing Zones is the practice of merging the volume of two adjacent Zones into a single Zone. We call this applying Air Boundaries but it can be referred to as 'adding a hole' or 'merging' in other software.

To combine Zones, simply left click the Aspect between two Zones and navigate to Air Boundary. You can now navigate to the 3D View and note the wall is not present.
