3D to 2D

Say I read a CAD/STEP file which has a 3D object that maps to a few shapes. Now I need to transform each of these shapes into a specific 2D projection like front or top or right or left etc. And I need those individual transformed shapes in 2D for my own purposes.

What is the best method to do it using open cascade?

use HLR classes.
