A 3D floor plan is a map of your home that is drawn in three dimensions, rather than the usual two dimensions. This can be helpful when you're remodeling, planning on a move, or just want to know where everything is. You can make a 3D floor plan by creating a floor plan in AutoCad and then adding one or more dimensions. To create the 3D floor plan, select the "3D" option from the "Drawing Style" drop-down menu. You can also choose to use one of the preset 3D styles to get started. Though, it is better to hire professional rendering services.
