I started the second video and realised that the creation of sketch 19 was missing. I don't know at what angle the line was or where it was located on the airfoil but I made it perpendicular to the chord and location was just near the front so I hope that is correct. When using the plane at angle command, The plane is created at a weird angle and I don't know how the angle came there. The angle is about 30 degrees but not exactly making it quite annoying. I checked if the origin was correct and it was at the some location as the origin of the whole plane which would mean that this should not occur? any idea how to fix it and possible more instructions on the location and angle of the line.
