Dynamo Directshape - unable to process all mesh

Hi everyone, I have recreated a mesh from vertices and indices and used the DirectShape.ByMesh and Springs TkMesh to Mesh node to import the mesh into Revit. However, DirectShape.ByMesh output some null even though all mesh was created.

I have tried:

  • Mesh.Remesh component but it doesn’t seem work
  • Scaling up & down the mesh works but its the wrong size as I want it to be on actual scale

Could anyone provide some advice?
