Preview visibility mode is available only for families (RFA files). It allows you to see how a view will be rendered in a project.

You can control preview visibility mode in the DBView element using the following methods.

To set preview visibility mode, use the setPreviewVisibility() method:

      
void setPreviewVisibility(bool isOn);
      
    

To check whether preview visibility mode is on, use the getPreviewVisibility() method:

      
bool getPreviewVisibility() const;
      
    

When you turn preview visibility mode on for GenSweep-derived elements, flags that are set in the FamElemVisibility attribute are checked, and an element is determined as visible according to the view's detail settings.

To check whether a view has a determined level of detail, use the isDetailLevel() method:

      
static bool isDetailLevel(OdInt32 nVisibility, OdBm::ViewLevelObjectDetail::Enum detailLevel);
      
    

For more details, see the preview visibility mode in the OdaBimApp sample application and read the OdaBimApp article.
