How do you cutout a angle in 3d extrusion?

[digitalhomeserviceswa]

Hi all, I'm having trouble cutting out an angled shape in a 3d extrusion. I created a shape in the sketch (3d) that has an angle and then performed an extrusion. Now on that angle that's now a 3d block, I want to again create an angle that I want to cutout of the 3d block. I place a new ketch plane where I want to draw the angle and then extrude (cutout) on that plane but each time I do so it's not following my angle. It always cuts out at  90 degrees from the drawn line. 

I'm stuck. Hope someone can help me.

Use the Sweep Tool.

Profile to cut is the triangle you have selected already.

Path is the blue line, but it can not be a construction line, change it to Normal Line.

Sweeping tool! Awesome Dave but still got an issue at the bottom where it won't cutout. Any ideas?

I figured it out mate. I had to create another sketch plane and draw another line and do another sweep to continue the cutout. Cheers mate much appreciate it.

here's my final image with the completed cutout.

Or the Path line was too high, and should be longer, to cover the complete cut.
