Struggling to Acheive my Intended Design

[Latheboy]

Hello,

I am trying to finalize what is intended to be a 3d adaptive machining project on the attached.  I am confused as to how to correct "Extrude 1" in the timeline, as well as to achieve the shape I am seeking.  The intention is to have the stair step shape with a 2" radius recess.  Hoping someone can assist with the proper steps to accomplish this.

Thanks

I have fixed your model's timeline but you will have to explain what the last 5 sketches in the timeline are all about.  Model is attached.

Thank you for fixing the error, I tried but couldn't figure out what the exact issue was or how to address it.

I don't know what the other sketches were, but I removed them.  I suspect that I went about the cad drawing the wrong way.  I am trying to get the step shape to be on a curve to match the contour behind it without the two outer corners.  

Never did this before so I am only guessing.

Thanks,

Steve

Hello,

I made some progress and the design appears to be what I am after, however, setup 2 has two elements on the manufacture side that I don't see on the design side as seen here.  I don't want the two vertical elements in the center of the part and can't seem to resolve this.  I have attached the updated file for review.

Thanks
