The below file has been made in Rh7. Running the optimization produces results as expected. When opening it in Rh6 and running the optimization, no good results are found. The “Max Planarity Deviation” (see panel) stays around its initial value.
Other planarisations based on similar definitions work well across Rh versions.
Thanks for looking into this.
