hello,

     in api, i want to auto-select the new entities created by 'copy method' , just like the following pictrue.

     to be more clear, i explain the detail steps:

  1. i select several circles in the open sketch.
  2. run macro to 'copy' the selected segments (the distance is up to you).
  3. after finishing 'copy' action, the macro auto-select the new circles that created by 'copy' method.
