I am working on a F1 car and need to test it with Falcon. But when I first created the car in Inventor, I put it on the XY plane, and as I see, the flows go on the YZ or other direction but definitely not the XY since I see the flows go from side to side of my car. I even changed the direction on the compass but I still does not work. Please help me on changing the plane orientation in Inventor. However, I heard somebody said we could redefine the sketches and put them in another plane but it seemed does not work on me, it messed up everything. Thanks!
