In the attached part you will see I have four angular cuts to make a trapezoidal pyramid. I made an angular plane, extruded the cut, etc. To make four of them, rather than do this process 4 times, I revolved the cut around the hole in the top. However, I was unable to do so with just a sketch. So, if I were to make this same part without the hole, how would I go about making my circular array of cuts- i.e., what would I revolve them around?
