class Draft_Modification(*args)¶

Bases: OCC.Core.BRepTools.BRepTools_Modification

Parameters

S –

type S: TopoDS_Shape
rtype: None

Add()¶

Adds the face F and propagates the draft modification to its neighbour faces if they are tangent. If an error occurs, will return False and ProblematicShape will return the ‘bad’ face.

param F

type F

TopoDS_Face

param Direction

type Direction

gp_Dir

param Angle

type Angle

float

param NeutralPlane

type NeutralPlane

gp_Pln

param Flag

default value is Standard_True

type Flag

bool

rtype

bool

Clear()¶

Resets on the same shape.

rtype

None

ConnectedFaces()¶

Returns all the faces which have been added together with the face <F>.

param F

type F

TopoDS_Face

rtype

TopTools_ListOfShape

static DownCast(t)¶

Error()¶

Return type: Draft_ErrorStatus

Init()¶

Changes the basis shape and resets.

param S

type S

TopoDS_Shape

rtype

None

IsDone()¶

Returns True if Perform has been succesfully called. Otherwise more information can be obtained using the methods Error() and ProblematicShape().

rtype

bool

ModifiedFaces()¶

Returns all the faces on which a modification has been given.

rtype

TopTools_ListOfShape

Perform()¶

Performs the draft angle modification and sets the value returned by the method IsDone. If an error occurs, IsDone will return Standard_False, and an error status will be given by the method Error, and the shape on which the problem appeared will be given by ProblematicShape

rtype

None

ProblematicShape()¶

Returns the shape (Face, Edge or Vertex) on which an error occured.

rtype

TopoDS_Shape

Remove()¶

Removes the face F and the neighbour faces if they are tangent. It will be necessary to call this method if the method Add returns Standard_False, to unset ProblematicFace.

param F

type F

TopoDS_Face

rtype

None
