Parameters

categoryId

The ID of the category.
hide
Type: SystemBoolean
True to make elements of this category invisible, false to make them visible.

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.

Exceptions
