class ShapeTolerance from ShapeAnalysis
---Purpose: Tool for computing shape tolerances (minimal, maximal, average),
-- finding shape with tolerance matching given criteria,
-- setting or limitating tolerances.
uses
Shape from TopoDS,
ShapeEnum from TopAbs,
HSequenceOfShape from TopTools
is
Create returns ShapeTolerance from ShapeAnalysis;
---Purpose: Empty constructor
Tolerance (me : in out; shape: Shape from TopoDS;
mode : Integer;
type : ShapeEnum from TopAbs = TopAbs_SHAPE)
returns Real;
---Purpose: Determines a tolerance from the ones stored in a shape
-- Remark : calls InitTolerance and AddTolerance,
-- hence, can be used to start a series for cumulating tolerance
-- <mode> = 0 : returns the average value between sub-shapes,
-- <mode> > 0 : returns the maximal found,
-- <mode> < 0 : returns the minimal found.
-- <type> defines what kinds of sub-shapes to consider:
-- SHAPE (default) : all : VERTEX, EDGE, FACE,
-- VERTEX : only vertices,
-- EDGE : only edges,
-- FACE : only faces,
-- SHELL : combined SHELL + FACE, for each face (and containing
-- shell), also checks EDGE and VERTEX
OverTolerance (me; shape: Shape from TopoDS;
value: Real;
type : ShapeEnum = TopAbs_SHAPE)
returns HSequenceOfShape from TopTools;
---Purpose: Determines which shapes have a tolerance over the given value
-- <type> is interpreted as in the method Tolerance
InTolerance (me; shape : Shape from TopoDS;
valmin, valmax: Real;
type : ShapeEnum = TopAbs_SHAPE)
returns HSequenceOfShape from TopTools;
---Purpose: Determines which shapes have a tolerance within a given interval
-- <type> is interpreted as in the method Tolerance
InitTolerance (me : in out);
---Purpose: Initializes computation of cumulated tolerance
AddTolerance (me : in out; shape: Shape from TopoDS;
type : ShapeEnum from TopAbs = TopAbs_SHAPE);
---Purpose: Adds data on new Shape to compute Cumulated Tolerance
-- (prepares three computations : maximal, average, minimal)
GlobalTolerance (me; mode: Integer) returns Real;
---Purpose: Returns the computed tolerance according to the <mode>
-- <mode> = 0 : average
-- <mode> > 0 : maximal
-- <mode> < 0 : minimal
