+---Boundary
Topological cell, such as a face, an edge or a vertex.
Role:
The Boundary objects are basic topological objects, such as the edge of a Pad. Some of them posess
a geometrical feature (planar face, rectilinear edge).
You will create a Boundary object (such as the TriDimFeatEdge object, which is derived, indirectly, from the Boundary object) using the
Shapes.GetBoundary ,
HybridShapes.GetBoundary ,
Sketches.GetBoundary or
Selection.SelectElement2 method. Then, you pass it to the operator (such as
ShapeFactory.AddNewEdgeFilletWithConstantRadius ). Note that, regarding V4 sub-elements, once the data of a CATIA Version 4 Model has been copied to a .CATPart, the sub-elements of the resulting .CATPart are
supported by the
Boundary object. The lifetime of a Boundary object is limited. In particular, after having call
Part.Update , the Boundary objects are usually no more valid.

Note:
Boundary objects cannot be selected into the specification tree. Note:For a
Boundary object, the object returned by the
AnyObject.Parent property is the master shape. For example, if we have:
Pad.2
!
!
+ V
! +---+
! / / !
+-- Pad.1 / / !
! / / one +------+
! +---+ / /! <--- Pad.1
! ! ! / / +
+-- Pad.2 ! !/ / /
! +------+ /
! ! /
+----------+
then, for the
PlanarFace number "one", the
AnyObject.Parent property returns the Pad.2 automation object (see
Pad ).
- Example:
-
This example asks the end user to select an edge (using the
TriDimFeatEdge object), and creates an edge fillet on this edge:
Dim InputObjectType(0)
Set Document = CATIA.ActiveDocument
Set Selection = Document.Selection
'We propose to the user that he select an edge
InputObjectType(0)="TriDimFeatEdge"
Status=Selection.SelectElement2(InputObjectType,"Select an edge",true)
if (Status = "cancel") then Exit Sub
Set EdgeFillet = ShapeFactory.AddNewEdgeFilletWithConstantRadius(Selection.Item(1).Value,1,5.0)
EdgeFillet.EdgePropagation = 1
Document.Part.Update
