  Update: Simplify, using body to do intersect.

  FeatureScript 2737;
  import(path : "onshape/std/common.fs", version : "2737.0");

  annotation { "Feature Type Name" : "Section Curves", "Feature Type Description" : "Intersect a plane with all faces" }
  export const SectionCurves = defineFeature(function(context is Context, id is Id, definition is map)
  precondition
  {
  // Pick Plane
  annotation { "Name" : "Cut Plane", "Filter" : EntityType.FACE && GeometryType.PLANE, "MaxNumberOfPicks" : 1 }
  definition.cutPlane is Query;

      // Pick Part, default pick ALL
      annotation { "Name" : "Scope (optional)", "Filter" : EntityType.BODY, "MaxNumberOfPicks" : 10 }
      definition.scope is Query;
  }
  {
  
      var targetBody =
          (definition.scope != undefined && !isQueryEmpty(context, definition.scope))
          ? qOwnedByBody(definition.scope, EntityType.BODY)   // 指定 Part → 取出所有面
          :qAllModifiableSolidBodiesNoMesh();
  
      opIntersectFaces(context, id + "intersectFaces1", {
              "tools" : definition.cutPlane,
              "targets" : targetBody
      });
  
  
      var PLN1 = evPlane(context, { "face" : definition.cutPlane }); // definition.CutPln is a Query, not a plane
      var sketch1 = newSketchOnPlane(context, id + "sketch1", {
      "sketchPlane" :  PLN1
      }); 
  
     
  
      skSolve(sketch1);   
      
      
  });
  

  Question:

  1. Sketch generated by FS, can't be used in Assembly. Is this fixed or any way to do it?
  2. How to project all the curves to sketch?

  });
  

  I debug from GhatGPT, and now it could generate the curves.
  Question:

  1. two box →8 curves (if I select 2 parts, correct, but default will generate 10 curves, some duplicate)
     1. Curve 1 and Curve 3 are the same
  2. How to create sketch with projection these curves?
