This appears to be all you need to get the stair element, from which you can get the topology (as one long list)

```
stid = mstr.GetAllStairsIds()
for i in stid:
	str1.append(doc.GetElement(i))

```

But if I try to get the landings and stair runs, it still revers back to the main elements which has been copied up into the multistorey stair. I really need to be able to identify the stair run and landing elements within the multistoreystair, otherwise it will be impossible to sort all the surfaces into any logical order
