algorithmic modeling for Rhino

Hey guys, 

What I would like to do is to be able to import a weaverbirdcommand (ExtractMeshEdges) from rhino to iron python or ghpython.

So what I planned to do was : 

import rhinoscriptsyntax as rs

rs.ExtractMeshEdges

But this command doesn't appear, and I guess because its referring to a plug-in and not to rhino itself.

So I was also thinking about that : 


import Rhino.PlugIns

But I don't find weaverbird there.

I hope that I was clear,

Best

You don't need weaverbird to extract mesh edges in python...you can do so looping through topologyedges.edgeline in the mesh object in rhinocommon. 

#m is the input mesh

el = []

for te in range(m.TopologyEdges.Count):
....el.append(m.TopologyEdges.EdgeLine(te))

a = el

Python list comprehension is also pretty neat for such cases:

edges = [m.TopologyEdges.EdgeLine(i) for i in range(m.TopologyEdges.Count)]

You could use the recently added node-in-code functionality (warning: can be slow). I'm not sure that you'll be able to import weaverbird as an assembly, but perhaps Giulio can chime in on that subject. I guess it all depends a bit on what you are trying to do. But in general you should be able to import most Python modules, .NET assemblies and GH components. Hope that helps.
