Thank you , I am looking forward for answer of that~ best wishes for you and FAR!

there are some issues about my FAR that I can't understand:confused: It's about the aerodynamic analysis, and to make sure it's an good example I put a lot of insane control surfaces as spoilers why the Cd line doesn't change? And the graph is almost as same as last one, because the y-axis has changed too. And when I click the button one more time without any change of spoilers or anything else, the graph changed... https://t.williamgates.net/image-940B_549BED2A.jpg' alt='image-940B_549BED2A.jpg'> Why is all of this???

Thank you, I just want to ask about the latest version~ Better if you put that at the top of the topic:D
