Find fascia on a given roof & get host curve

Hi,

For a given roof, how can we find if there is a fascia that references the roof and which curve of the roof hosts the fascia?

Fascia can span multiple roofs, so I would not expect a Fascia.Host property (and no such property exists)

There is the HostedSweep..::..ReferenceCurve Property but that requires as an input the reference of the curve that hosts the object.

I tried the "temporary deletion" trick, but if the fascia is hosted by multiple roofs then it is not deleted when one of the host roofs is deleted.

We could use the temporary deletion trick with Dynamic Model Udpate's GetModifiedElementIds, but that's getting pretty convoluted and the need to find the curve hosting the fascia still exists.
