-=== Constraints and Objectives === +        - For this example do the following: 
-    - Open the //Plan Constraints/Objectives// block  +          - Click the //Edit// button 
-      - Enter the //Constraints// for the planning volumes first +          - Click //Add Structure// and select (Skin) 
-        - These are the "hard stops/non negotiables" for the plan +            - Add a max set to 85.5 
-        - These doses will be decided per the users' department protocols +          - Click the //OK// button 
-        - For this case we will enter the following for the targets first: +<WRAP center round info 85%> 
-          - prostate min 79.2Gy +After the target constraints have been entered, it's generally good practice to test the plan feasibility. The Feasibility calculation is run by clicking //calculate// at the bottom of this block. The Feasibility calculation is based solely on the constraints and it should be used to ensure there is a possible solution (plan) that can meet the specified constraints. Establishing Feasibility is often an iterative process in order to get appropriate constraints established for a particular plan. In other words, the user may need to enter a constraint, check the feasibility, then progressively tighten the constraint and check the feasibility until the plan is no longer feasible. It is recommended practice to start by obtaining a feasible plan utilizing only target constraints (and a global max constraint) then add OAR constraints as desired. Remember, using a narrow range of constraints can improve the optimizer performance and improve the resolution of the Pareto surface navigation.

-      - After the target constraints have been entered, the user may start the Feasibility calculation by clicking calculate in the Feasibility block. The Feasibility calculation is based solely on the constraints and it should be used to ensure there is a feasible plan possible. The Feasibility calculation may be an iterative processes in order to get appropriate constraints established for a particular plan. In other words, the user may need to enter a constraint, check the feasibility, then progressively drop the constraint and check the feasibility until the plan is no longer feasible. It is recommended practice to start by obtaining a feasible plan utilizing only target constraints then add OAR constraints as desired. Remember, using a narrow range of constraints can improve the optimizer performance and improve the resolution of the Pareto surface navigation. +        - The feasibility should return as passing, if not, please confirm your plan parameters match those shown throughout this walkthrough and try again
