Help needed - Secondary Auxiliary view drawing !

[Any1]

Hi,

I need help finishing this ... I got to draw a primary and a secondary auxiliary view in order to see adequately the oblique surface...

I guess I understand much of how to do it, the problem is I don't get how to finish this with the hidden lines etc. ...

Any inputs would be AWESOME !!!!!!!

Thank you very much

I don't quite understand the top left sketch. I think it is the view perpendicular to the surface that has been cut, but your lines suggest it is derived from the cross section on the far right. I don't think it helps describe much.
That far right cross section needs some heavier lines to be complete.
Personally, I would have added a top view, as I think that would describe enough.

What is this for?
