Crisalix offers a very precise tool that can be used to fine-tune any breast procedure called Refinement Lines. 

Refinement Lines is located in the Tools menu, on the right-hand side of the simulator screen.

1.  Once finished your simulation with the specific breast procedure tool, select Tools and open the Refinement lines menu.
2.  Select one of the predefined views to activate the specific lines.
   Select one more time to deactivate that specific view/lines.
3.  The lines are made of different segments. Click on the specific line to visualize the movements you can make. 
4. Drag or move the mouse to make the necessary adjustments.
5. Select Mirror if you want to have the same line activated on the opposite side.
6. Line selection length will help you modify the length of the line -therefore, the range of the area or movement covered-.
7. Observe how the volume totals change according to your movements.
8. Select Undo or Redo at the bottom of the menu if needed.
