package ShapeCustom
|
|
|
|
---Purpose: This package is intended to
|
|
-- convert geometrical objects and topological. The
|
|
-- modifications of one geometrical object to another
|
|
-- (one) geometrical object are provided. The supported
|
|
-- modifications are the following:
|
|
-- conversion of BSpline and Bezier surfaces to analytical form,
|
|
-- conversion of indirect elementary surfaces (with left-handed
|
|
-- coordinate systems) into direct ones,
|
|
-- conversion of elementary surfaces to surfaces of revolution,
|
|
-- conversion of surface of linear extrusion, revolution, offset
|
|
-- surface to bspline,
|
|
-- modification of parameterization, degree, number of segments of bspline
|
|
-- surfaces, scale the shape.

returns Shape from TopoDS;
|
|
---Purpose: Applies modifier to shape and checks sharing in the case assemblies.

|
|
DirectFaces(S: Shape from TopoDS) returns Shape from TopoDS;
|
|
---Purpose: Returns a new shape without indirect surfaces.
|
|
|
|
ScaleShape (S: Shape from TopoDS; scale: Real) returns Shape from TopoDS;
|
|
---Purpose: Returns a new shape which is scaled original

|
|
returns Shape from TopoDS;
|
|
---Purpose: Returns a new shape with all surfaces, curves and pcurves
|
|
-- which type is BSpline/Bezier or based on them converted
|
|
-- having Degree less than <MaxDegree> or number of spans less
|
|
-- than <NbMaxSegment> in dependence on parameter priority <Degree>.
|
|
-- <GmaxDegree> and <GMaxSegments> are maximum possible degree
|
|
-- and number of spans correspondingly.
|
|
-- These values will be used in those cases when approximation with
|
|
-- specified parameters is impossible and one of GmaxDegree or
|
|
-- GMaxSegments is selected in dependence on priority.
|
|
-- Note that even if approximation is impossible with <GMaxDegree>
|
|
-- then number of spans can exceed specified <GMaxSegment>
|
|
-- <Rational> specifies if to convert Rational BSpline/Bezier into
|
|
-- polynomial B-Spline.
|
|
-- If flags ConvOffSurf,ConvOffCurve3d,ConvOffCurve2d are Standard_True there are means
|
|
-- that Offset surfaces , Offset curves 3d and Offset curves 2d are converted to BSPline
|
|
-- correspondingly.
|
|
|
|
ConvertToRevolution (S: Shape from TopoDS) returns Shape from TopoDS;
|
|
---Purpose: Returns a new shape with all elementary periodic surfaces converted
|
|
-- to Geom_SurfaceOfRevolution
|
|
|
|
SweptToElementary (S: Shape from TopoDS) returns Shape from TopoDS;
|
|
---Purpose: Returns a new shape with all surfaces of revolution and linear extrusion
|
|
-- convert to elementary periodic surfaces
|
|
|
|
ConvertToBSpline (S : Shape from TopoDS;
|
|
extrMode : Boolean; revolMode: Boolean;
|
|
offsetMode: Boolean; planeMode: Boolean = Standard_False)
|
|
returns Shape from TopoDS;
|
|
---Purpose: Returns a new shape with all surfaces of linear extrusion, revolution,
|
|
-- offset, and planar surfaces converted according to flags to
|
|
-- Geom_BSplineSurface (with same parameterisation).
