 # Double the perceived number of connections

Hello all,
I am having some trouble with a python script I and a colleague are writing that would take in a mesh and iterate through the all the vertices and get them to recognize their neighbors so as to be able to act on them. For some reason it seems as though I am getting double the perceived number of connections.
It would be monumentally helpful if you could glance over my code and tell me what might be causing this issue.
Here is the python script:

import Rhino
import scriptcontext

def GetEdges(x):

``````b = x.Faces

edges = []

for i in range(b.Count):
face = b.GetFace(i)
if face.IsTriangle:
A = face.A
B = face.B
C = face.C

if A < B:
edges.append((A,B))
else:
edges.append((B,A))

if B < C:
edges.append((B,C))
else:
edges.append((C,B))

if C < A:
edges.append((C,A))

edges.append((A,C))

A = face.A
B = face.B

while count < len(edges):
scriptcontext.escape_test()

if edges[count] == edges[count-1]:
edges.pop(count)

print len(SuperVertex.SuperFriends.myNeighbours) On my computer your post has a variety of font sizes, and the one on your main program is impossible to read. So without knowing all you’ve written, I only ask whether you are getting twice as many because you are processing in such a way that you are getting both the connection of (e.g.) A with B and B with A, which the program treats as different and you assume are the same?
