Reloaded Family Visibility Parameter not Working Correctly-Revit Memory Question

[rvtquestions]

Before I begin I will preface:

1. There are no visibility overrides or issues with view templates, etc in the project
2. No special use of shared parameters or global parameters associated to the family in question
3. For privacy agreements, I cannot share the family & project.

To simply the situation, I have a family that has a nested annotation which its appearance is driven by a parameter we shall call "X". I added a new filled region in the nested annotation family and created a new parameter for its visibility which has dependency on the parameter "X" I also changed the parameter name "X" to "Y". I reloaded the edited annotation into the family and reloaded that into the project.

Upon, reloading, all the family instances in the project did not display correctly. The newly added hatch is not displayed and some other option is displayed. Logically I ran through these troubleshoot steps:

1. Perhaps renaming the parameter was not a good idea, so I went back and edited the family and made sure all parameters were working correctly, I also renamed it back to the original and even deleted the family in the project and reloaded a "fresh" new version. Still, it would not display correctly.
2. I then loaded in the family into a new document as well as other Revit versions, and they all work perfectly fine.
3. I deleted my temp folder, and opened up a backup version of the Project, purged everything, and reloaded the family, and still it would not display correctly.
4. At this point, I am at a loss of what could be the issue. I suspect it has to do with some memory storage of Revit in the same manner imported CAD file instances are not accessible through the project navigator or purge but must be removed through the API.

Any idea what is the issue and where Revit is "storing" some sort of information that is preventing the reloaded family to work correctly?

Hard to troubleshoot without seeing something that can confirm and verify what we think you are describing.  I'm curious to know though, what do you mean by: "some other option is displayed"?  Can you tell us what displayed?

Yea sorry unfortunately I cannot share but perhaps I can try to recreate the issue. To answer your question, lets use a triangle data symbol as an example. There are 3 conditions: White fill, Black fill, Half white fill/Half Black fill. Originally, I had the white conditions with no fill but then added filled regions for a white fill and half white fill conditions. And again, I am 100% positive the parameters are working correctly, they work fine in any other project except the one in question. When I load the family into the problem project, when I switch to any type W, B, HW/HB, they all appear full black. I edit the project family and the parameters work fine and display correctly in the family editor but in the project it does not even if no black fill is supposed to show. It is as if Revit has some stored memory of the family setting, which is bizarre to me.

Have you checked the named Fill Patterns under Additional Settings (Manage Tab) in the Project?

-So, the family displays properly in a new/blank project?

-If so, then something in your project is causing the improper display problem.

-Visibility parameters are often set for coarse, medium and fine detail level.

-Check the views/view templates for detail level, and visibility settings for both the nested and host families.

Filled region types and fill pattern definitions in the project govern. Make sure those are defined properly in the project.

Thank you @ToanDN, @cbcarch, @barthbradley for all the replies and support. As I've mentioned I am well aware of how all that works and understand the different levels of visibility management from project object styles, view templates, filters, view detail, etc. I am at a loss because everything I know is correct.

1. No overridden graphics
2. Family works in family editor and other projects, including reloading into projects that had the family already
3. Filled Region and fill styles all match, they are just white or black solid fills
4. No weird background that would make everything black

[barthbradley]

So, just to clarify: the Filled Regions under Additional Settings (Project) are named and defined exactly the same as the Filled Regions in the Family?  

[rvtquestions]

Well if you mean Additional Settings / Fill Patterns...yes its just using the same generic solid fill pattern

[barthbradley]

Yes; that what I'm referring to. The Fill Pattern definition in the Project rules. Meaning that if you had an identically named Fill Pattern in the Family, but the Project and the Family used a different fill pattern/color for that named Fill Pattern; the Project's Fill pattern/color would be used when you loaded the family into the Project.  Same thing happens with Materials.   

...actually, Detail Items is what I should have directed you to.  Look in your Project Browser under Detail Items=>Fill Regions.
