How do I flex along a guide curve?

Question asked by Paulo García on Mar 11, 2018

I'm working on creating a NACA duct to put on the body of an aerodynamic shell for a vehicle. The duct is going to be placed at the leading edge of the car, where the car has some slight curvature. I plan on manufacturing the part out of fiberglass without taking the flex into account. I'm assuming that the part will be flexible enough so that when I bolt it down it will flex onto the contour of the curve. However, I am unsure of how to CAD this. Using the flex tool, I can't find a way to bend the part to the exact curvature of the car using the few inputs given in the flex tab (angle, radius, axis, and trim plane).

 

How would I go about bending this part so it matches the contour of the car? I have attached pictures of the car and duct below.

Here is the duct in the assembly. As you can see the duct is flat whereas the car has a contour.

Here it is from a side view.

This is the contour line of the car. How do I flex the duct along this specific line?

 

Thank you for all help provided.
