We are upgrading our library to 2014 and every family that upgrades is missing the thumbnail preview in Windows Explorer and the file open dialog in Revit 2014. The same Revit 2014 rfa upgraded using the journal script also does not preview in 2015. This only occurs for 2014 families upgraded this way. I can upgrade the content library to 2013 or 2015 and all thumbnails in Windows Explorer and Revit 2013 and 2015 are visible. The thumbnail is not being saved for Revit 2014 families and it is definitely a problem with the family itself.

I am using the journal scripts provided by autodesk found here:
C:\Program Files\Autodesk\Revit 2014\en-US\Utilities\ContentBatchUtility

I have also tried the journal scripts delivered with 2015 and the problem is the same when the files are upgraded using Revit 2014. Makes sense since they have not been upgraded since 2010. In fact they are the same for every year.

So I thought if perhaps I could tweak the journal script but I do not know the correct format for changing the option in the save-as dialog to "Regenerate if view/sheet is not up to date." I am wondering if this will force the thumbnail to save. I identified the journal entry created when that option is checked:

Jrn.Data "SaveOptionsData" _
, 3, 5983, 1 _
, 0, "Custom"

I thought it might slip in at this point, but of course I dont know what I am doing here. If anyone has a suggestion or know the format I would appreciate it.

Jrn.Command "Internal" , " , ID_REVIT_SAVE_AS_FAMILY"
Jrn.Data "File Name" , "IDOK", namepath
Jrn.Data "SaveOptionsData" _
, 3, 5983, 1 _
, 0, "Custom"
Jrn.Command "Menu" , "Close the active project , ID_REVIT_FILE_CLOSE"

Also, any links to guides on editing journal files for this type function are greatly appreciated. I have been searching the forums for hours but am not finding them to either not clicking deep enough or using the wrong search terms.

thanks.
