Hello Sushil,
Yet another way to do it is to build the composite layup and foam core on a surface like we were doing. Then create a 3D model of the finished composite sandwich, mesh it, and import the 3D solid mesh in ACP to map the composite layup onto the solid mesh. You will find more information about this technique in the help:

Let me know how it goes.
