1.  Introduction

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

Image Added

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 a center of a model.

2. Red graphics calculations

1. Draw plane parallel to table plane through MIC center: 
   Image Added
2. Distance from model center to section-plane calculated for all azimuth.
3. Minimum radius from step 2.2 selected.
4. Graphics is drawn as deviation from minimum radius.

3. Black graphics calculations

1. Model is projected on table plane:

2. Distance from model center to projection calculated for all azimuth:

   Image Added	MIC is drawn in red color
   Image Added	indicates MIC center
   Image Added	indicated Girdle center mass (model center)

   3. Graphics is drawn as deviation from minimum radius from step 2.3

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.
