extrude remove from curved surface

scott_schroeder961

I am struggling to remove the curved sections already sketched onto the part. Everything I have tried won't work. I used Split Body to project the sketch onto the curved parts (and the flat parts). I can extrude remove the flat parts but I can't seem to do anything with the curved section. I have insluded the link of the project.

Hello Scott. Rather than using an extrude, perhaps creating a surface using the edges of relevant part and then using the surface to split the part and discarding the unwanted section. - Scotty

I had success from the individual suggesting I down load the featurescript for tangent planes. I got the project set for machining but when I try to export the file in a STEP format and load it to a commercial machinist, the file comes out with the middle sketch (showed in above drawing as grey part) showing which I don't want. I am not sure how to get rid of it in the final project machining file. I have the link showing the final project as it should be machined.
