  23. This macro makes a list of holes for drilling  from a solid
  24. 1. Select a solid object that has holes in it and run the macro
  25. 2. It only collects info on holes that are parallel to the Z axis- I don't have a 4 or 5 axis mill at the moment
  26. 3. It pulls the center of the hole bounding box and the XLength for it's diameter
  27. 4. It will place a list of the holes on the clipboard
  28. 5. Uncomment the line that starts with '#Draft.makeLine' and manipulate it, if you want to see lines down the center of each hole.
  29. 6. Manipulate the line that starts with  'holelist.append' to make the list fit your own needs- I've put the ZMax at the ZMax of the solid's bounding box
  30. because I want to make sure that my drill tip doesn't collide with anything on the top of the part. YMMV.
