I want to perform a repeatable osteotomy with a certain shape using Slicer. Essentially I need a modified plane Markup, where the section crossing the bone is not simply horizontal, but for ex. a Z-shape pattern. As I am not a programmer in any way, I sought to consult the community here first for help. Is there an extension that allows for the construction of more complex markups? Or is an all new, custom markup required for this? Thanks in advance
