View.SetCategoryHidden

Description:
Sets if elements of the given category will be visible in this view.

Remarks:
This affects 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 setting this value may not affect the actual visibility of elements of this category in the view.
