text: Hi,
  I run he script below and pick the points in the order mentioned in the rhino file attached.
  The rectangle gets printed, but when i try to run something on it like areacentroid i get “Parameter must be a Guid or string representing a Guid”. And this is because points 2 and 3 are too close to each other.
  Why is this happening? how can i avoid it?
