CATIA V5 - Flattening and transferring features in Part Design

This is a demo for a bent aerospace beam. The faces are unruled. To add to the difficulty, it's not really an intelligent part. To bring it into a 2D drawing, we need to flatten it and transfer all the cuts and fillets into the final version. It's almost like reverse engineering the whole part again.You can extract some details such as the beam profile as well as the overall length to produce the extrusion length. It's a laborious task but the result is worth the effort.
