Hi All,

I’m currently using a Python node created by [jeremy@learndynamo.com](mailto:jeremy@learndynamo.com), which I have edited to suit my needs (Create one elevation marker with all 4 elevations turned on). The output I get from this script is the Elevation MArker, but I am looking to get a list out of all the individual elevation views created. Please see the script below of what I’m using. Any advice would be appreciated. I do have a basic \> intermediate knowledge of Python. Thanks in advance!

Create a new array just after `if toggle == True`, say…

`elevations = []`

And where you have `ele = eleMarker.CreateElevation()`, store the returned ViewSection in your elevations array. You can do this simply by doing…

`elevations.append(eleMarker.CreateElevation(doc, doc.ActiveView, index))`

And then `OUT = lst, elevations`
