Chapter 4: Grading
******************

  The PAD System Pattern Design offers tools and options for user to grade pieces, facilitate user to adjust piece sizes. 
  
Size Setting
=============

  Before grading the pieces, user needs to set sizes. 
  
How to set sizes
-----------------

  #. Select Menu [Grade] - [Working Sizes...]; 
  
  #. The dialog box appears, enter total sizes and click [Apply] button, system will generate the sizes and take the middle size as Medium automatically. 
  
      |gr_image001|
	  
  #. User can set Medium size, or modify the size number/special/break(XS,S,M,L,XL). User can set maximum of 5 break groups.

      |gr_image002|
	  
	  For example:
	  
	  |gr_image003|
  
  |gr_image003_1|
  
  |gr_image007|
  
  |gr_image007_1|
  
  |gr_image008| 
  
Ways to grade
===============

  The PAD System Pattern Design offers three ways to grade pieces. 
  
Grade in X,Y
--------------

  #. Select the desired segment/point(or more points to be graded in the same values); 
  
  #. Select Menu [Grade]-[Grade Info](or press hot key **Ctrl+J**), to open the Grade Info Dialog Box; 
  
  |gr_image004|
  
  User can use regular grading list for regular grading (step value between each size group is the same):
  
  |gr_image005|
  
  User can use irregular grading list for irregular grading (steps between each size is different):
  
  |gr_image006|
  
  .. note:: The irregular grading list also can be used for regular grading.  However, irregular grading can be performed in irregular grading list only.
  
Grading Arrows
----------------
  
 By using Grading Arrows, user doesn't have to recognize the grading direction depending on the negative or positve value.  User can select desired step value(positive), and click the arrow button to control the grading direction.  
 
Open the window
^^^^^^^^^^^^^^^^^

  Before using Grading Arrows, user needs to open the window:
  
  Click Menu [View] - [Show Widget] - [Grading Arrows]
  
  |gr_image009|
  
Perform grading by Grading Arrows
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

  #. Select the point(s)/segment; 
  
  #. Select step value; 
  
      .. note:: 
	  Allow user to enter step value as requried. 
	  
	  #. Pull the menu bar to bottom; 
	  
	     |gr_image014|
	  
	  #. Select [Edit], open the [Evolution] Dialog Box; 
	  
	  #. Select unit, and then click [New].  Enter deisred step value and click [OK].
	  
	     |gr_image015|
		 
	 In V7.0, user can enter desired step value directly. 

     	  |gr_image016|
		  
  #. Select the desired size to be graded; 
  
  #. Click the arrow button to perform grading; 
  
      .. note:: It increases according to the current step value each time you click the arrow button
    
      For example: 
	 
	  to grade the hem of the T-shirt: 
	  
	  #. Select the desired hem line:
	  
	     |gr_image010|
		 
	  #. Select desired step vale (enter it directly in V7.0)
	  
	     |gr_image011|
	 
	  #. Select the size to be graded
	     
		 |gr_image012|
	  
	  #. Click the arrow button to perform grading:
	  
	     |gr_image013|

	 |gr_image022|: the difference between two neighbouring sizes
  
  #. Regular/Irregular 

     |gr_image023|: Regular Grading 
	 |gr_image024|: Irrgular Grading
	 
  #. Grade/Modification
  
     |gr_image025| Black eye icon: Cumulative of the grading.
	 
	 Add value to existing grading, you don't have to delete the former value.
	 
	 |gr_image026| Red eye icon: Current modification.
	 
	 Temporarily hide the graded value, the new-entered value is added to the graded value. 
	 
	 |gr_image027|
	 
	 
Grading Library
----------------

  Allow user to create a grading library with the frequently-used grading evolutions.  User can use it directly.
  
  For example:
  
  |gr_image028|
  
  Click the small arrow in front of the preset grading item, user can see the specific values.
 
  |gr_image029|
    
Drop-down menu
^^^^^^^^^^^^^^

  |gr_image030_1| 
  
  .. note:: Examples:
  
       |gr_image030|
	  
	   |gr_image031|

	 |gr_image042|
	 
Grade piece by applying grading library
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  
  After building a grading library, user can use the grading library to grade piece direcly, which increases the efficiency of pattern-making.
  
  How to do:
  
  #. Select the desired point or segment; 
  
      |gr_image043|
	
  #. Click the corresponding grading item in the library, like: Hem
  
     |gr_image044|
	 
  #. Repeat the former step to grade other point or segment
  
      |gr_image045|
