how to same condition at mesh verte

hi!

may i ask one question? (mesh vertices same condition)

i want same list item condition at multiple meshes.

for example, surface subsrf is made of list index (0,1,2,3) in orderly!

mesh face is not different all

i hope that all meshes are made in orderly list number

Sorry, I have absolutely no clue, what you are trying to say... Corners of a mesh face or 4point surface are always ordered.

When you inspect a GH mesh face, you see the indices of the vertices in the whole mesh. So if you have a mesh with 100 vertices, face 1 might point to vertices (0,1,2,3) and face two can look like (100,1,2,99). This only means, that vertex 100 and 99 are connected with vertex 1 and 2 to form a face.

The face normal (inside/outside) is deteminded by vertex order. So if the mesh wraps around, you are bound to find some vertices traveres in reverse order. This in neccessary to have all faces point outward.
