Generate a 2D shape for each face of a 3D object?

I have a 3D object and I need to generate a 2D drawing for each of the four long surfaces. The resulted 2D shapes needs to be grouped by layers of which names to reflect the tool used and the depth of the mechanisation. The number used for the tool needs to be something smaller than the minimum width of the shape. T12 = tool with a maximum diameter of 12mm. The name for depth will be just a number reflecting the depth of mechanisation in mm.

Please, can somebody help-me to create a definition to solve this problem? Thank you.
