Public Function GetCategoryHidden ( 
	categoryId As ElementId
) As Boolean

)

member GetCategoryHidden : 
        categoryId : ElementId -> bool 

Parameters

The ID of the category.

True if the category is invisible (hidden), false otherwise.

Exception	Condition

Remarks

This checks only if the category is set visible or invisible individually. Other Revit mechanisms may also affect the visibility of elements of this category, including:

• The category classes settings for model categories, annotation categories, import categories or analytical model categories.
• View filters.
• Elements hidden individually in the view.

Thus the return value may not reflect the actual visibility of elements of this category in the view.
