Modeling help needed

I was trying to model the tail fin(vertical Stabilizer) for an aeromodel design. I inherited a dwg file of the tailfin with some poorly defined ribs that help shape the fin. The fin tapers back and up.

My problem - I need to put in a brace which starts from the front of the lowest rib and goes back and up to the front of the topmost rib. and a pair of slots similar to the ones already modelled but further up towards the front. I hoped that a sweep feature on the assembly would do it but i am unable to create a rail and constrain it properly. Could someone please show me or tell me how these types of features could be modelled?

Another issue i had was to model a plastic film covering for the fin. An aeromodel uses a heatshrink monokote film. How would i model something like that in inventor.

The requisite files have been uploaded to dropbox.-

Thanks in advance.

I assume you want something like the attached.

If you created your models about the origin planes, it would make things easier and simpler.

Also the assembly features will not automatically migrate to the individual model part files.
