#boolean subtract spiral

Am trying to cut a spiral space out of a unusually shaped vessel. I have constructed a spiral tube but am having quite a time getting it to conform to the exterior of the vessel so that I can boolean subtract, leaving the vessel with acontinuous slot through its sides from bottom to top. Is there a way to construct a "cutter" for this procedure by using the "data" from the location of the vertices of the vessel (x,y,z)? Or am I spinning my wheels here (not so unusual in itself)? thnaks all ian mckay

Hi, Ian. Did you loft the "spiral tube" in the lofter using a helix path? If so, this should work as a boolean "cutter" as long as its length is greater than the width of the vessel. But it's unclear what you mean by "conform to the exterior of the vessel"…could you clarify?

Thanks for the thought, Connie…sorry if my question was unclear. ian
