//   To create your own scale from scratch,  
//      Make a cube to act as your base.  Texture it as you like and turn it phantom.
//      Make 9 more cubes and stack them on top of each other.   
//      Link the 9 cubes together and then link that stack to your "base" cube
//      Copy the [CheckPorportions] animation and the [Proportional Avatar Sizing} notecard into the base
//      Drop this script into your base cube. 
//      Your stack of cubes should transform into a "Natural" scale for a 2 meter avatar

This is a BETA implementation of an avatar sizing scale
It is designed to provide a simple scale with which you can measure the proportions of your avatar.
 
There are 2 scale modes enabled.  
The default  "Natural" mode is based on a  8 head scale. 
Realistic human avatars should be approximately 8 heads tall,  and just under 2 heads  wide.
 
It also supports a "Heroic" mode based on a 9 head scale.  
Heroic avatars will have longer legs and should be wider at both the shoulders and hips.  
There are some studies that show this is considered more attractive in many western cultures.
 
The scale has alternating Dark and Light "bars" in it to help you see the important locations..
 
To use the scale,  place it on a flat surface so that the base of the scale is close to the surface but not beneath it.
Touch the scale and use the menu buttons to set the mode you desire (Default is Natural) , or select the [SET Height]  button.
Enter the desired avatar  height ( in METERS) in the text box ( without hitting return,  Use the submit button...).  
 
The scale should adjust its configuration or size and give you a message as it does so.
 
DO NOT SIT ON THE SCALE UNTIL YOU HAVE SET THE PROPER MODE AND SIZE
The scale will attempt to "guess" at, and set, a proper sit location.  This will NOT work if you are already sitting..
 
Once the scale has reset you can sit on the scale.  There is an animation provided to pose you appropriately. 
You should be positioned in the middle of the base with the scale running up the middle of your avatar.
Your feet should be close to the ground. 
 
Touch the scale again and use the {Move Up] or {Move Down] buttons to adjust your position until your feet are on the base.
( Note)  this BETA version of the scale has issues and you may see your avatar JUMP the first time you try to adjust.
 
*********************************************
 
What you SHOULD see if your "Natural" avatar is correctly proportioned
 
The first (top) bar should go from the top of your head to the bottom of your chin.
Your shoulders should be approximately the same width as the scale.
Male nipples should be slightly above or at the bottom of the second bar.
Female nipples should be slightly below the bottom of the second bar.
Your "belly button" should be just under the third bar.
Your crotch should be at the bottom of the fourth bar, 1/2 way down.
Your wrists should also be in approximately the same place,  1/2 way down.
Your knees should be above the 6th bar,  at least 2 bars above the ground.
Your Feet should be on the base.
 
When using "Heroic" mode the following adjustments should be made..
Both Male and Females nipples should appear just under the bottom of the second bar.
Male crotch should be 1/4 - 1/3 of the way down from the top of the 5th bar.
Knees should be under, instead of above, the bottom of the 6th bar.
 
*******************************************
Unfortunately, you will not be able to make avatar size adjustments while sitting on the scale.
To adjust body size, you must stand,  use [edit appearance] to make changes, and sit on the scale again to check.
The scale is supposed to remember the adjustments you made, but you may have to adjust it again ( its BETA)
********************************************
 
As a rough guide,  the following  appearance parameters can be modified to achieve the best "fit"
 
   In the BODY section,  use the HEIGHT slider.
 
   In the HEAD section, first use the HEAD SIZE slider, and then the HEAD STRETCH
       ( you may want to play with the CHIN section  sliders, but I recommend you come back to those later)
 
   In the TORSO section,   Use SHOULDERS to set the shoulder width.  
       (Muscular torsos will extend beyond the scale slightly)
       Use the ARM LENGTH slider to position your wrists
       Use the TORSO LENGTH slider to move your belly
 
   In the LEGS section, use LEG LENGTH to adjust the position of your knees and get your feet on the ground.
       Adjust HIP LENGTH to modify your belly button and crotch locations.
