Help with modelling rocket fin I'm trying to model a simple rocket but got stuck at the fins.
I've made the rocket body, then proceeded to extract two faces from the place I want the fins to be attached to and converted the faces to a path. There's another path that show the path I want the fin to follow, like in the following picture:



The problem is that when I select the fin guide and select the fin profile as bevel target, I get:



What I was expecting is that the fin begin at the path selected in the first image, and be face to face with the rocket body, something like in this 2d sketch:



How do I achieve what I want?
Personally I would do this with simple mesh modeling.

Start with one vertex and Extrude it to create faces. F2 add-on (bundled with Blender) could be your friend here.

After making the shape you will need to snap it to selected edge on Rocket body.



At the end you can use this method: How to make a circular array using offset object as center? to position your fins and add Solidify modifier.
