Extrude Sides

Folks, I'm at wits end here.  File is shared and link is below.

For a specific need, I'm making a NACA duct shape (will not be used as a proper NACA duct) but as well to get some practice making things like this.  Guessing some lofting might be another way to go but simply extruding some bits away (removing) sure seems quick and dirty all of which suit my simplistic needs for this part. 

However, in this picture notice, the two darker area's above and below the actual NACA shape seen in the middle.  Why oh why can I not extrude those two darker areas? As in Remove Extrude. 


Stinks to be lost but this is one of those times. I look forward to seeing/reading what I'm missing.

Many thanks everyone.

    It's because Sketch 1 is before Extrude 12, so you can either a) reorder the sketch after and fix any broken references, or b) create another sketch on the face of the extrude and "Use" the edges from Sketch 1.

    ...assuming this is the shape you are after.  If so here is another approach.

    1) Make your first Extrude off of Sketch1, in the up direction to the distance you need (right side pic).
    2) Make your second Extrude off of Sketch11, using the "Intersect" Boolean operator and a Second end position condition (bottom pic).

    Fantastic. All I need to do is learn about orders....Of course if I had a brain I would have exhausted all (orders etc) but didn't. You all are simply the best and I cannot thank you all enough. Stay well, PC
