Abaqus-CAE, Sweep cut problem

I am attempting to cut the portion as indicated in the image. I am using a sweep cut, but I'm not achieving the desired result. Although I can cut it, the final position is not as intended. Note: The first two points are collinear, but the third point is not. I have also attempted solid extrusion, but I can cut through the top two points due to their collinearity, but I cannot cut through all the three points. I have made the cut as marked 40 times; do I need to repeat it 40 times, or is there a way to perform it all at once? How can I achieve the desired result? Please provide guidance.
