Wasp aggregation


Hello Folks,
I am trying to aggregation. Writing what I want to achieve:

  1. create polygon
  2. Find the curve middle
  3. find the normal and vector
  4. rotate the polygon at different angle lie (30,45,60,90)

Here I have achieved Normal and vectors. But while doing aggregation using wasp then it is showing an error. I have also attached files of that. Kindly help me to solve it.
