Adding vertical mullions/fins to exterior facade


New rhino user here, I have created a skyscraper which I want to add vertical mullions/fins to the facade. The tower tapers from bottom to top as you can see from the attached image. What is the best way to add these vertical fins/mullions? Use the contour function? I want to make sure these vertical lines will follow the taper curve of the building.


One idea would be to use the Fin command selecting any curve on the surface and the surface itself to define the direction of the fin. This can be done numerically and the taper would be preserved. Use Project, Contour or Intersect (with some planes) to generate the curves.
