[ll3167]

Hi! I am a new user of Dynamo. I want to deconstruct curtain wall geometry in revit model into points. I found that Curves.DeconstructPolyCurve can help but I could not find it. Is there anyone can tell me why?

It’s a node from the Lunchbox package:

LunchBox

Have you installed it from the package manager? If so, you need to visit https://provingground.io/tools/lunchbox/ to get the full installer
