Creating a Model of the Building
Use WallMan to create a model of the building.

Figure 1. A 3D model of the building, consisting of planar polygons. Glass windows and glass patio doors are indicated in light blue and wooden doors in yellow.
This example does not specify the floor plan, or give exact locations or number of interior walls, wooden doors or windows, but instead, it highlights the steps to create these structures.
You are encouraged to create your own floor plan and internal structures.
