I'm in the process of drafting the interior curves for the handle in the ADVANCED tutorial for a vacuum cleaner. I'm including a screenshot of where I am in the tutorial. The instructions say to check the FLIP button if the blue vector line is pointing toward the centerline. There is no illustration that indicates if my blue vector line is correct as is. Does my screenshot look correct or, should I check the Flip button? I've been trying to get this operation to work correctly for a few days. Thanks for any help!
