Issue with Sketches created after shell tool

Thanks for taking the time to read this thread. I have a frustrating issue, one that I have not encountered on previous parts.

I searched the forum, but am probably looking for the wrong key words...or I'm just an idiotic noobie

My issue is this:

I started the IPT normally.

1. Created the sketch
   
2. using a rectangle (construction lines) to define my required dimensions, I used the spline (vertex) tool to draw out 1/2 of my shape.
   
3. Then I mirrored the spline around a center axis.
   
4. exited the sketch and extruded the design
   

Up to this point any sketch created is perfectly aligned on the axis.

Once I use the Shell tool, every subsequent sketch is skewed by about 7 degrees

What am I doing wrong? I have attached my IPT file for anyone wanting to take a look.

I appreciate ya'll help!

Create your sketches on the Origin workplanes rather than on part faces.

JD,

Much Appreciated! should have thought about that!:face palm:

Thanks!!

I must be missing something. When I create the work plane, it is skewed by the same amount as the previous sketches. This is even prior to creating the shell. I can make the wp work, but what is causing this issue in the first place? Id rather fix the problem than the symptom.

When the main section is a relative rectangle this does not happen.

Thanks
