HI i need merge Mesh. MergeAllCoplanarFaces API(IN GRASSHOPPER) for Mesh(or SubD)
In Python C # or Rhinoscriptsyntax,…???
Is there a way for MergeCoplanarFaces Work in grasshopper as well as this performance in Rhino for( Mesh Brep and Subd)?
Of course I wrote MergeCoplanarFaces command according to the relevant API for BREPOnly!!, but does not act for Mesh and SUBD

  private void RunScript(Brep Brep, ref object brep, ref object Result)
  {
    if (null != Brep)
    { brep = Brep.MergeCoplanarFaces(RhinoDocument.ModelAbsoluteTolerance);
      Result = brep;
      brep = Brep;}

Looks like this api hasn’t been added yet
is there another way to do it with Python vb or macro?( in grasshopper)

Perhaps MeshNgonList.AddPlanarNgons is the magic?

thanks @Mahdiyar please fix this one

 private void RunScript(Mesh mesh, bool trimmedTriangles, bool MergFace, ref object brep)
  {
    brep = Brep.CreateFromMesh(mesh, trimmedTriangles);
    if (MergFace == true){
      brep.MergeCoplanarFaces(RhinoDocument.ModelAbsoluteTolerance);     
      }
