private class SortCriterion from SelectMgr
---Purpose: This class provides data and criterion for sorting candidate
-- entities in the process of interactive selection by mouse click
is
Create returns SortCriterion from SelectMgr;
Create(thePriority: Integer from Standard;
theDepth, theMinDist, theTol: Real from Standard;
PreferClosest: Boolean from Standard)
returns SortCriterion from SelectMgr;
---Purpose: Defines parameters of selection criterion:
-- - Priority: selection priority
-- - Depth: distance from the view plane to the entity
-- - MinDist: distance from the clicked point to the entity on the view plane
-- - Tol: tolerance used for selecting candidates
-- - PreferClosest: specify whether closest object is preferred even if
-- if has less priority
