Detailed Description

Rebuilds a Shape by making pre-defined substitutions on some of its components.

In a first phase, it records requests to replace or remove some individual shapes For each shape, the last given request is recorded Requests may be applied "Oriented" (i.e. only to an item with the SAME orientation) or not (the orientation of replacing shape is respectful of that of the original one)

Then, these requests may be applied to any shape which may contain one or more of these individual shapes

Supports the 'BRepTools_History' history by method 'History'.

BRepTools_ReShape()

BRepTools_ReShape::BRepTools_ReShape

(

)

Returns an empty Reshape.

Member Function Documentation

Apply()

virtual TopoDS_Shape BRepTools_ReShape::Apply ( const TopoDS_Shape &  theShape, const TopAbs_ShapeEnum  theUntil = TopAbs_SHAPE  )

virtual

Applies the substitutions requests to a shape.

theUntil gives the level of type until which requests are taken into account. For subshapes of the type <until> no rebuild and further exploring are done.

NOTE: each subshape can be replaced by shape of the same type or by shape containing only shapes of that type (for example, TopoDS_Edge can be replaced by TopoDS_Edge, TopoDS_Wire or TopoDS_Compound containing TopoDS_Edges). If incompatible shape type is encountered, it is ignored and flag FAIL1 is set in Status.

Reimplemented in ShapeBuild_ReShape.

Clear()

virtual void BRepTools_ReShape::Clear ( )

virtual

Clears all substitutions requests.

CopyVertex() [1/2]

TopoDS_Vertex BRepTools_ReShape::CopyVertex	(	const TopoDS_Vertex &	theV,
		const gp_Pnt &	theNewPos,
		const Standard_Real	aTol
	)

Returns modified copy of vertex if original one is not recorded or returns modified original vertex otherwise.

CopyVertex() [2/2]

TopoDS_Vertex BRepTools_ReShape::CopyVertex	(	const TopoDS_Vertex &	theV,
		const Standard_Real	theTol = -1.0
	)

Returns modified copy of vertex if original one is not recorded or returns modified original vertex otherwise.

History()

Handle< BRepTools_History > BRepTools_ReShape::History

(

)

const

Returns the history of the substituted shapes.

IsNewShape()

Standard_Boolean BRepTools_ReShape::IsNewShape

(

const TopoDS_Shape &

theShape

)

const

Checks if shape has been recorded by reshaper as a value.

IsRecorded()

virtual Standard_Boolean BRepTools_ReShape::IsRecorded ( const TopoDS_Shape &  shape ) const

virtual

Tells if a shape is recorded for Replace/Remove.

Merge()

template<typename TCollection >

void BRepTools_ReShape::Merge ( const TCollection &  theParts, const TopoDS_Shape &  theProduct  )

inline

Merges the parts to the single product. The first part is replaced by the product. The other parts are removed. The history of the merged shapes is presented by equal ways.

ModeConsiderLocation()

virtual Standard_Boolean & BRepTools_ReShape::ModeConsiderLocation ( )

inlinevirtual

Returns (modifiable) the flag which defines whether Location of shape take into account during replacing shapes.

Remove()

virtual void BRepTools_ReShape::Remove ( const TopoDS_Shape &  shape )

virtual

Sets a request to Remove a Shape whatever the orientation.

Replace()

virtual void BRepTools_ReShape::Replace ( const TopoDS_Shape &  shape, const TopoDS_Shape &  newshape  )

inlinevirtual

Sets a request to Replace a Shape by a new one.

replace()

virtual void BRepTools_ReShape::replace ( const TopoDS_Shape &  shape, const TopoDS_Shape &  newshape, const TReplacementKind  theKind  )

protectedvirtual

Replaces the first shape by the second one after the following reorientation.

If the first shape has the reversed orientation then the both shapes are reversed. If the first shape has the internal or external orientation then:

• the second shape is oriented forward (reversed) if it's orientation is equal (not equal) to the orientation of the first shape;
  
• the first shape is oriented forward.

Status()

virtual Standard_Integer BRepTools_ReShape::Status ( const TopoDS_Shape &  shape, TopoDS_Shape &  newsh, const Standard_Boolean  last = Standard_False  )

virtual

Returns a complete substitution status for a shape 0 : not recorded, <newsh> = original <shape> < 0: to be removed, <newsh> is NULL

‍0: to be replaced, <newsh> is a new item

If <last> is False, returns status and new shape recorded in the map directly for the shape, if True and status > 0 then recursively searches for the last status and new shape.

Reimplemented in ShapeBuild_ReShape.

Value()

virtual TopoDS_Shape BRepTools_ReShape::Value ( const TopoDS_Shape &  shape ) const

virtual

Returns the new value for an individual shape If not recorded, returns the original shape itself If to be Removed, returns a Null Shape Else, returns the replacing item.
