CATIA V5: How to realise some chamfered edges on a compressor helix?

Hey guys,
I'm actually working on some helix compressor parts, in detail on the main compressor helix itself of a G-compressor.

The edges of this helix need to be chamfered and so I now have a question how to realise these chamfered edges on the ends of the helix without any idea.

Please have a look at the following pictures to understand what's the precise need:

You can see these red lines which show the geometrical arrangement of the chamfered edges. My problem is that I don't know how to realise some kind of projection of a chamfered line onto a bent surface of the helix that in result I get a kind of cutting line or something like this.

Can anybody give me a way to solve the problem? If it is to complicated, I don't need the precise sequence of working steps, the way is enough that I can discover and develop it on my own!

Thanx a lot and greetz from germany,
Matse

There is no need to project a line. Instead, there are two easy ways to do it:

a. Add a CHAMFER to the edges you want to eliminate, or

b. Add a DRAFT to the faces on the ends of the helixes
