How do I remove a portion of an extruded face, but not all of it.

Because the rear face is larger than the front face, I'd start with the rear face and draw a triangle section to remove, then extrude/remove out

I am trying to remove the highlighted part in the screenshot. The tab on the end of the part needs to slope down, which I am trying to achieve by removing the highlighted section.

Something like in the picture attached.

If I delete the faces then I am left with a hollow section and I can't work out how to do have keep the sloping face solid. I have posted the url to the document below:

Hi.
1 draw a sketch on the flat front face of your part 
2 Project the outline of the face with the "Use" feature.
3 Add a line in the sketch where your want the cut.
4 extrude the triangular sketch region with the following parameters "remove" "up to face" and select the back face of that tab.
Does that make sense? If not I'm sure someone will demonstrate.
Cheers, Owen.

@mark_rogers151, it seems like you're pretty new to CAD modeling. It's helpful to learn by doing, but it would also help to get you up to speed on the basics. Going through the Onshape fundamentals tutorials would probably answer a lot of your questions.

Perfect...Thanks John. That was so simple.
