To cut a 3D model into sections at a certain interval with the ability to save these sections into a vector, you will need a 3D modeling or CAD software that has the ability
to create sections or slices. Popular options include AutoCAD, SolidWorks, Rhino, and Blender. Import your 3D model into the software, create sections or slices at the desired intervals, and save them as vectors. The specific steps and commands will depend on the software you use.
