class MinRadiusDimension from AIS inherits EllipseRadiusDimension from AIS
---Purpose:-- Ellipse Min radius dimension of a Shape which
-- can be Edge or Face (planar or cylindrical(surface of
-- extrusion or surface of offset))
uses
Shape from TopoDS,
Elips from gp,
Pnt from gp,
Pln from gp,
Ellipse from Geom,
Plane from Geom,
Surface from Geom,
Presentation from Prs3d,
PresentationManager3d from PrsMgr,
Selection from SelectMgr,
Projector from Prs3d,
Transformation from Geom,
PresentationManager2d from PrsMgr,
GraphicObject from Graphic2d,
ExtendedString from TCollection,
ArrowSide from DsgPrs,

raises ConstructionError from Standard
is
Create (aShape : Shape from TopoDS;
