BRepBuilderAPI_MakeShell Class Reference

Describes functions to build a
shape corresponding to the skin of a surface.
Note that the term shell in the class name has the same definition
as that of a shell in STEP, in other words the skin of a shape,
and not a solid model defined by surface and thickness. If you want
to build the second sort of shell, you must use
BRepOffsetAPI_MakeOffsetShape. A shell is made of a series of
faces connected by their common edges.
If the underlying surface of a face is not C2 continuous and
the flag Segment is True, MakeShell breaks the surface down into
several faces which are all C2 continuous and which are
connected along the non-regular curves on the surface.
The resulting shell contains all these faces.

 BRepBuilderAPI_MakeShell ()
 Constructs an empty shell framework. The Init
function is used to define the construction arguments.
Warning
The function Error will return
BRepBuilderAPI_EmptyShell if it is called before the function Init.

 BRepBuilderAPI_MakeShell (const Handle< Geom_Surface > &S, const Standard_Boolean Segment=Standard_False)
 Constructs a shell from the surface S.

 BRepBuilderAPI_MakeShell (const Handle< Geom_Surface > &S, const Standard_Real UMin, const Standard_Real UMax, const Standard_Real VMin, const Standard_Real VMax, const Standard_Boolean Segment=Standard_False)
 Constructs a shell from the surface S,
limited in the u parametric direction by the two
parameter values UMin and UMax, and limited in the v
parametric direction by the two parameter values VMin and VMax.

void Init (const Handle< Geom_Surface > &S, const Standard_Real UMin, const Standard_Real UMax, const Standard_Real VMin, const Standard_Real VMax, const Standard_Boolean Segment=Standard_False)
 Defines or redefines the arguments
for the construction of a shell. The construction is initialized
with the surface S, limited in the u parametric direction by the
two parameter values UMin and UMax, and in the v parametric
direction by the two parameter values VMin and VMax.
Warning
The function Error returns:

virtual Standard_Boolean IsDone () const
 Returns true if the shell is built.

BRepBuilderAPI_ShellError Error () const
 Returns the construction status:

const TopoDS_ShellShell () const
 Returns the new Shell.


 operator TopoDS_Shell () const

BRepBuilderAPI_ShellError BRepBuilderAPI_MakeShell::Error ( ) const
  • BRepBuilderAPI_ShellDone if the shell is built, or
  • another value of the BRepBuilderAPI_ShellError
    enumeration indicating why the construction failed.
    This is frequently BRepBuilderAPI_ShellParametersOutOfRange
    indicating that the given parameters are outside the bounds of the surface.
