Keep loft centerline straight

[joskate22]

Hi, I'm kind of new to Fusion 360, I've been looking to create a loft with a centerline in the middle, but I need to keep the part in the middle straight but it is curving for some reason. Is there anything I could do to prevent that? Or is it better to use rails? Red line indicastes what I would like to have.

Thanks!

Not with just a Centreline. physics will not allow that.

Two choices, Extrude centre panel, and loft one side wing, mirror the other side.

or make the front back edge sketch’s (2) as needed and use 3 rails.

Might help....
