What is the index argument in the command:

bpy.ops.mesh.select_linked_pick(deselect=False, delimit={'SEAM'}, index=1729)

Is it possible to find it with python ?

  • $\begingroup$ it's the edge index,and yes you can find it but how exactly you want to find it in python $\endgroup$ – Chebhou Apr 30 '16 at 17:46
  • $\begingroup$ This command line was run on a basic UV Sphere and this sphere was not as many edges. Is that there are different index ? $\endgroup$ – pistiwique May 1 '16 at 18:57
  • $\begingroup$ sorry I didn't understand your comment, but if you could describe what you are trying to accomplish we may find the answer $\endgroup$ – Chebhou May 2 '16 at 17:02
  • $\begingroup$ Sorry for my late answer. I finally found a solution without using this operator but, i'd ever like to know where this index come from. $\endgroup$ – pistiwique May 7 '16 at 7:55
  • $\begingroup$ For exemple, if i display the edges index of an selected face, i have these four edge index : 552, 540, 511 and 555. The face index is 255. Now, if i use the select_lincked_pick operator, The index in the operator is 1729. So , where does this index come from if it is that of an edge ? $\endgroup$ – pistiwique May 7 '16 at 8:03

For the operator bpy.ops.mesh.select_linked_pick(deselect=False, delimit={'SEAM'}, index=1729) the index is taken from the closest element to the mouse cursor and it is calculated as follows :

  • For Vertices : index = vertex.index.
  • For Edges : index = len(vertices)+ edge.index.
  • for Faces : index = len(vertices)+ len(edges) + face.index
