Get Mesh Faces, Get Mesh Vertices

[Riccardo]

Hello All,

I'm planning to write two scripts for editing mesh objects : extrude a mesh face, bridge between mesh faces

and I was wondering if there is any plan for implement get mesh faces or get mesh vertices?

or if I can use any alternative methods ?

Many Thanks
Riccardo

Hi Riccardo,
Are you referring to specific RhinoScript functions that have not been ported to python? I can't find any with those types of names.

If the RhinoScript functions don't exist, I can probably help you mix a little RhinoCommon into your python script to get at what you need.
Thanks,

Hi Steve,

Yes I was referring to the RhinoScript functions!
anyway before reading your post I did not realize that RhinoCommon can be used with python
So I spent around 8 hours looking in to it ( I do not have a background in programming) and finally come out with this :

Python Code:

import Rhino
import scriptcontext
import System.Guid
import rhinoscriptsyntax as rs
 
 
def PickMeshFace():
   
   
    # get the mesh face from rhino viewport
    PickMeshFace = Rhino.Input.Custom.GetObject()
    PickMeshFace.GeometryFilter = Rhino.DocObjects.ObjectType.MeshFace
    PickMeshFace.SetCommandPrompt("Select Mesh Face")
    PickMeshFace.Get()
   
    if PickMeshFace.CommandResult()!=Rhino.Commands.Result.Success:
        return gs.CommandResult()
   
    # Rhino.Input.Custom.GetObject .Object() to Rhino.DocObjects.ObjRef
    objref = PickMeshFace.Object(0)
   
    return objref
 
def GetFaceIndex(objref):
   
    # Rhino.DocObjects.ObjRef .GeometryComponentIndex to Rhino.Geometry.ComponentIndex
    MeshFaceIndex = objref.GeometryComponentIndex
   
    return MeshFaceIndex.Index
 
 
Face_1_Ref = PickMeshFace()
 
print "This is the mesh ID"
print Face_1_Ref.ObjectId
print "This is the Rhino.Geometry.Mesh "
print Face_1_Ref.Mesh()
print "This is the Face index"
print GetFaceIndex(Face_1_Ref)

with this i can get index of the selected mesh face and the mesh id
if you see a better solution in order to get the (face index and meshID) or you can foresee any problem with this I would appreciate if you post a correction... thanks

Hi Riccardo,
My mistake, I was looking in the wrong spot in the RhinoScript functions and just missed these. I just added them to python so they should be available in the next V5 Beta. You can also get them from gituhub at
https://github.com/mcneel/rhinopytho...erinterface.py
but it looks like you've already solved your problem by just directly accessing RhinoCommon

Thanks,

Thanks for sending the Github link !
