Hi, I am struggling to figure out how to make a cut in 3 different directions/planes so to speak.

I have done the 3 sketches on the model in which I would like to have a swept cut from the first 2 skecthes, and that swept cut to be kept within the boundary of the 3rd sketch on top? So in effect the swept cut will be breaking out the side curve, whereas I would like it to follow the curve offset. The model is pretty much self explanitory when you see it.

Could someone shine a light on how I would do this please?

Cheers,

Tom
