1. Introduction

MIC is the maximum circle that may be inscribed (MIC) in the girdle outline along with the section of the model in the circle's plane:

MIC is drawn in red color
indicates MIC center
Girdle outline is drawn in blue

2. Calculation

  1. For table plane:
  2. Minimum (farest from table plane) and maximum (nearest to table plane) girdle points are detected and search range determined:
  3.  In that search range number of planes (parallel to table plane) are drawn:
  4. In each plane  the maximum circle that may be inscribed is built.
  5. And from that circle's one with maximum radius is selected. That will be MIC.
