In the 'Detailed' usage, you can add apartments and side units to your building. Units can be added in bulk from the right side or individually within the floor card on the left side. The size of each unit can be adjusted after placement from the left side or managed in bulk as small, medium, or large. When placing multiple units in bulk, you can also edit the distribution of each type of apartment from the right side. Additionally, you can modify the construction and core settings.
