[Therion] Aligned cross sections for multiple passages

Hi folks, Next crazy question; I would like to do cross sections of multiple passages that are aligned according to each other. I can see how to do multiple cross sections, and presumably I can manually shift them into positions and hope I get it right. But is there a way to get Therion to place them all relative to each other? As an example, I have used the effect here with a bitmap-rendered survey, done manually: http://www.cavinguk.co.uk/info/cresSurv/CrescentFinalOverlap.gif Thanks for any suggestions. Tarquin
