Finding hidden elements

[Anonymous]

What are the ways to find a hidden element in Revit file? 

My steps: 

1. Check Reveal Hidden Elements

2. Go to Visibility and check if some elements are unchecked. 

Do you know some other ways to find element that is hidden (and you don't know how it was hidden).

For elements that are Hidden (with a capitol H, meaning as per official Revit terminology), using the Reveal Hidden Elements feature and zooming extents is all you need.

For elements that are hidden (with a lower case h, meaning not visible for any reason), here is a list of possible reasons:

1. The object or category is temporarily hidden
2. The object or category is hidden in the view
3. The object is being obscured by another element
4. The object's category or subcategory is hidden in the view
5. The object is outside the view's view range
6. The view's far clip depth is not sufficient to show the object
7. The object resides on a work set that is not loaded within the project
8. The object resides on a work set that is not visible in the view
9. The object resides on a work set that is not loaded in a linked file
10. The object resides on a work set that is not visible in a linked file
11. The object resides within a group (detail model) and it has been excluded from the group
12. The object is part of a design option that is not visible in the view
13. The object is part of a linked file that is not visible in the view
14. The object has one or more of its edges overridden to display as '<Invisible lines>'
15. The object is a family and none of its geometry is set to be visible in the view type
16. The object is a family and none of its geometry is set to be visible at the view's detail level
17. The object is set to not be visible at the category's detail level
18. The element has been placed outside the view's crop region (visible extents)
19. The element is an annotation object and does not reside entirely within the annotation crop region
20. The object's phase settings or the view's phase settings prevent the object from displaying in the view
21. The view's discipline is prohibiting the visibility of the object
22. The object is affected by a filter applied to the view
23. The object is subject to an element override, set to background color
24. The object is subject to a category override, set to background color
25. The object style is set to background color
26. The object is constrained to a scope boxes that is not visible in the view
27. The extents of the object itself don't permit it to be seen
28. The object is a mass, and 'Show Mass' is turned off
29. The object's host view has been deleted (area boundaries)
30. The view's scale is prohibiting the object's visibility
31. The object is a linked instance with coordinates too great for Revit to handle
32. The user has incorrectly identified the link instance to which the element belongs
33. The object is in a link that is not in its correct position

I don't know who to credit the list to, but I saw it on the internet somewhere.

Reveal Hidden Elements is the only only to find elements that are hidden BY ELEMENT in the current view. You can find out which Categories that are hidden in the current view by checking in your view's VG (Model and Annotation Tab), as well as find out what Filters (Filter Tab) are applied to the current view that are affecting the visibility and graphics of a particular elements in the view. And then there are Links and Phase Filters, of course. But, as far as finding those particular elements you made invisible By Element, no is no other way to find them without using Reveal Hidden Elements.

In 2011, Dave Jones of Revit Forum put together a wonderful list of 33 possibilities that an element may not be visible in view. I keep a hardcopy of it next to my workstation.

AHA! That's what I had put in my post above. Didn't know who to credit. Thanks!
