how to make a 3d model of the shape

I would like to make a model of iris mechanism using fusion360 and I don't know how to draw the curve bellow which is surrounded in yellow. I would like to know how I should calculate and draw it.

The most straightforward way of making a 2D shape into a 3D object is by extruding it. An extrusion is simply pushing the 2D shape into the third dimension by giving it a Z-axis depth (see Figure 3.17). The result of an extrusion is a 3D object with width, height, and now, depth.
