You can select which of the various categories of gbXML surface objects should be applied to the model. Selected surface types will be listed in the Navigator, displayed on the Edit screen as planes of various colours, rendered on the Visualisation screen and included in Radiance daylighting and EnergyPlus simulations as shading surfaces.
Surface types that are not selected are not removed from the model entirely and can be displayed again by changing selections on this dialog.
The default surface selection were set on the Import BIM/gbXML Model dialog when initially importing the model.
Note: For surface planes that are shown, the Component block shades and reflects option on the Constructions tab can be unchecked to prevent particular planes from being included in the EnergyPlus simulations.
