I think you’re asking about the contour shapes used by the ExtrusionXXX functions. If so, then look at the section on Drawing curves, Drawing Curves | Babylon.js Documentation.
Specifically, if you just want a circular contour to extrude then you can hand generate it, or use, say, the ArcThru3Points function:

var arc = BABYLON.Curve3.ArcThru3Points(first, second, third,20,true, true)
where 
var first = new BABYLON.Vector3(1,0,0);
var second = new  BABYLON.Vector3(0,1,0);
var third = new  BABYLON.Vector3(-1,0,0);

Then, pass arc.getPoints() to the extrusion function
