[Closed] spline booleans via mxs ?

i need to use the spline boolean subtraction functionality via mxs but I havn’t found any functions to do so in the reference. the nearest I have found is splineOps.startSubtract but that just activates the ‘subtract mode’ for the user to click and i need this to be automated. A long time ago I remember looking into this but I can’t remember if I ever got it to work. Is there a function somewhere that I’ve missed or has someone got an equivalent way to achieve this?
