If you change the ordering of the vertices, you will also have to change the facet definitions to match the new ordering of the vertices. This page has diagrams that might be helpful for understanding how the planar solids are defined:nhttps://support.lumerical.com/hc/en-us/articles/360034901573-Planar-solid-Simulation-Objectn
