Sheet Parameter - BuiltInParameter.SHEET_COLLECTION_NAME is null for all Sheets

[Sean_Page]

According to the SDK, there is a new BIP SHEET_COLLECTION_NAME parameter that I assume should give us the Collection Name, but when I attempt to use it in a PVP or get retrieve the value, it is always null.

Is there a reason why this parameter wouldn't be working or providing a value?

Also, it does not show up in RevitLookup.

The parameter in the image is a Integer.

AsString should return null because is the wrong type. The AsValueString return Yes, probably this parameter is a Yes/No.

My understanding of sheet collection, is when you create a group to hold certain sheets. accessed from UI via right click, and choosing new sheet collection. however, the feature and the value seems working fine on my end.. I hope i didn't miss understood your question

verifying that via snoop

@ricaun, I was using the image to show the Sheet Collection Name parameter wasn't in the list.

@Moustafa_K,

Yes, the collection themselves are working fine, but there is a Built In Parameter that is supposed to return the Name of the collection and that parameter doesn't seem to be working as it returns "null" like it isn't found.

I just tried from C#

sheetView.get_Parameter(BuiltInParameter.SHEET_COLLECTION).AsValueString()

seems working fine still.

but yes SHEET_COLLECTIONNAME  returns null indeed

Is not showing because the SHEET_COLLECTION_NAME is not supported in that element type, the category sheet I guess.

I suppose the SHEET_COLLECTION_NAME parameter is used in the SHEET_COLLECTION element.

Snoop the SHEET_COLLECTION and check if is in there.

Boo, and duh all at the same time. Well, I would argue that it should be available on the sheet as well 🙂

Thanks Luiz!
