One can either create "sketches" within Autodesk Simulation Mechanical or Multphysics (Algor) within the YZ plane, then mesh those outlines using the 2D Mesh Generator and analyze as 2D elements. This is common and a powerful method in reducing analysis time while providing cross sectional results detail.
It is also possible to create and export sketch data from other CAD packages as DXF or DWG, then open those files directly into Simulation.
