How to quickly add geometry when modeling?

Click "Customize-Interior Modeling 2.0" and select a room to enter the modeling interface.

Select the geometry, you can change the size of the geometry in "Geometry Attributes-Parameter Setting". You can also change the material properties of the geometry in "Geometry Attributes-Style Setting".
