Yes good shout with YouTube, IÔÇÖve watched a few just I seem to get stuck on this mesh again. IÔÇÖve saved my files locally but the files wonÔÇÖt open so IÔÇÖve had to start again. IÔÇÖve noticed now thereÔÇÖs a gap on airfoil at the Center point. Any ideas? Should I delete the last but one coordinate and make sure it goes back to 0? DoesnÔÇÖt seem to completely follow my geometry.
