Recently there has been a subtle change to how filters are added to the list (in v2015 of Revit):
In Revit 2013, when you add view filters, the most recent one will always be added to the end of the list.
In Revit 2015, when you add view filters, they appear to go in just below the selected filter in the list. Once you add a new one, it does not become selected. That means that if you add several in succession, they won't go in the order you add them - they will be added in reverse order just below whatever you happened to have selected.
To correct the Sort Order:Initially I thought that you either have to live with the mess, or remove the filters and add them back in again. Of course, if you do this, you lose all the filter override settings.
We actually have the ability to move filters up and down the list (Edit. Thanks to various comments - this paragraph has been corrected).
Revit 2015 - Adding new filters
- Click on the filter in the list that you want new ones to follow
- Add the first filter
- Then click on the one you just added
- Add the next one
- Click on that one
- Add again
- etc - until you have the list as desired.
This method does give you much more flexibility than how it worked in v2013. However, it is confusing as hell until you see what it is doing.
I noticed that you can also add several filters at once, but it does not necessarily add them in the order that they are shown in the 'Add Filters' list.
There is also the curious question of why the list of filters in the Filter dialog box is not alphabetical. Only Autodesk can solve that for us . . . . .
