1.  Introduction

Radius variation plot graphics is used in most reports for stone symmetry indication:

On X axis azimuth is shown.

On Y axis deviation is shown.

MIC is the radius of the maximum circle that may be inscribed.

Girdle center mass is used as the center of a model.

2. Red curve line calculations

1. Draw plane parallel to table plane through MIC center: 
   
   
2. In that plane distance from model center to diamond out-line calculated for all azimuth.
   

   

   	MIC is drawn in red color
   	indicates MIC center
   	indicated Girdle center mass (model center)
   	Diamond out-line is drown in blue color

3. Minimum radius from step 2 is selected.
4. Graphics is drawn as deviation from minimum radius.

3. Black curve line calculations

1. Model is projected on MIC plane:
   

2. Distance from model center to projection out-line calculated for all azimuth.

   

   	MIC is drawn in red color
   	indicates MIC center
   	indicated Girdle center mass (model center)
   	Projection out-line is drown in black color

3. Graphics is drawn as deviation from minimum radius from chapter 2 step 3

4. Notes

• If you have any question, please ask it in comments or send e-mail to developer.
• If you find mistake, please describe it in comments or send e-mail to developer.
• If you use report.dll 2.6.5.1 or later MIC will be used as model center.
