[Closed] Compound Shape – Shape Boolean in 3dsmax 2020

ShapeBooleanObject

thanks , i did search the documentation i don,t know how i missed that.
i’ll be helpful like intersection.

fn AddIntersect A =
(
	deSelect A
	select A[1]
	(macros.run "Shapes Compounds" "ShapeBoolean")
	A[1].operation[1] = 3
		
	for s=2 to A.count do
	(
		A[1].AppendOperand A[1] A[s] true
	)
	convertToSplineShape A[1]
)


AddIntersect (selection as array)

the resulted shape from shapesBoolean become closed shape on converttospline. even after manually deleting the segment it gets closed on deselect. anyone know why ?
